Dynamic GridView - Insure The Input For The Textboxes Is An Integer
Dec 17, 2009
I have a web page with 5 checkboxes and 2 textboxes per checkbox. When the user checks one or more checkboxes the corresponding textboxes become enalbed for UI. I need to insure that the input for the textboxes is an integer-that I will do with a validators. There is a gridView on the same page. When the user checks one or more checkboxes the 2 columns of the gridView rows become active for input through enabled textboxes.
There are 4 columns in the grid. The minimum number of rows enabled are 2 and the maximum are 26. The UI for the grid's textbox input is numbers. Those numbers have to be equal to or less than the total. How do I validate UI of numbers(integers) into the grid's dynamically generated textboxes and then add the total and compare it to the alloted total? I prefer to do this with the code behind - using VB.NET - rather than with ASP.NET or absolutely not javascript.
I have a form that requires 5 columns of textboxes that the user will populate. By design I will provide the first row but, the user will need the ability to add or delete subsequent rows. Is there an easy way to approach this requirement?
I've been trying to learn enough to develop the family tree diagram and making progress.[URL]..It illustrates many of the drawing, saving, re-opening, editing, drag/drop features that the family tree diagram would need, and is a good starting point.
To adapt this for the project, after searching for snippets online, I've tried to add dynamic insertion of a label as a start (eventually, it should be a textbox that the user, in runtime, can enter text into, save, re-open, edit). But, I can't get this to work. No errors display, but I must be doing something wrong.
Here's the label code which I've so far appended at the end:
I started editing an existing code (basicaly to learn vb) without any real previou experience. Well let's get to the point; I have a form that gathers data from db ordering by user ID (on click count). I have one DataGridView with a list of user, some have data in db, some have not. I came so far that if I CLICK on a user that have data, all data is dissplayed in 6 dinamyc textboxes. If user has no data inly first (emty) row with 6 dinamyc textboxes is created.
Then I have a button that simultaneously adds a row of dinamyc textboxes bellow and multiplyies textbox04 (name is clickcount & 4) and textbox05 and displays the result in textbox06. I want to add a messagebox that shows if textbox04 & 05 are empty and in that case exits sub. Of course if they are not empty, their sum should be multiplyed in textbox06 (on 2 decimal places exact) Here is my code so far:
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'Reset warnings
I am creating dynamic text boxes on button click and then showing values on another button click. It works fine until I use ajax updatepanel. In that case values are not shown when I hit second button. My aspx code is:
If i have multiple textboxes with the same Id and name in a form, how to fetch there values separately in vb.net? in javascript iv used fetched them like this
I have a code in Save Button, and part of it, a code that checks if the dynamic text boxes that has been created is empty. But when the system runs, it only check the first set of text box and an an message appears "Collection was Modified; enumareation operation may not execute.".
Here's the code:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click Try For Each txt As TextBox In TextBoxes2 If String.IsNullOrEmpty(txt.Text) Then
I have to delete all the textboxes after I clicked the Save button, I have a delete code here that deletes the textboxes one by one. I'm just starting in vb.net.
Public Class FunctionProcessor Dim TextBoxes1 As List(Of DateTimePicker) = New List(Of DateTimePicker) Dim TextBoxes2 As List(Of TextBox) = New List(Of TextBox)
I have 10 textboxes. I want to make a certain number of these textboxes visible. The user enters a number from 1 to 10 to determine how many textboxes are visible.The textboxes are named textbox1, textbox2, .... , textbox10How do I set up a simple for loop to accomplish this?
My problem is that I have a gridview with five rows and an unknow number of columns. What I want to do is in row 1 I want each column to be a textbox and in the next row create a button/link to create a report for each column. My problem is only the last column is being changed to a textbox. Here is my code.
In my form, A user can do some stuff on my program which will create a new tabpage with a text box on it. The user also selects the name of the tab, which is then the name of the textbox with a "2" on the end of it.
What I need to know is how to get the texts from however many tabpage's textboxes there are and combine them into one textbox, as a sort of receipt.
What I was thinking, because I have this method of removing all the tabpages, is using a code like the one below maybe to do the job, not sure how I would alter it to work though. [code]...
I have an ASP project which references a WCF service. Does exactly half of what I need.
A button on the page calls a function from the WCF, which returns a list of objects (variable names). When returned, the vb code dynamically adds textboxes to a panel on the page.[code]...
I have a form with many text tboxes; 5 text boxes (columns) in each row; each row will become a record.[code]...
Ho do I write these values from text boxes in a gridview control? If a value is changed in any of the text boxes then the gridview control should refresh with updated data.
I am able to write this data in a gridview with the following code but it is badly written [code]...
In the player vs computer tic tac toe game I've been working on there are 2 boolean arrays (one for the computer and one for the player) that track which cells have been taken. When all other moves have been exhausted I would like the computer to play a random cell. To do this I am trying to gather the indexes of all False values from the 2 arrays and add them to another dynamic integer array. The computer will then choose randomly from the new array. The two Boolean arrays are plyrTaken and cmptrTaken. The dynamic array is occupied.
Here I declared the arrays: Public Class Form1 Private occupied() As Integer Private plyrTaken(8) As Boolean Private plyrPairs(14) As Boolean
Here I got the dynamic array ready for use: Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load ReDim occupied(0)
And here is the code I have attempted: For index As Integer = 0 To 8 If plyrTaken(index) = False And cmptrTaken(index) = False Then ReDim Preserve occupied(UBound(occupied) + 1) [Code] .....
In the last block of code I was just trying to print the contents of the array to a list box so I could see if it was working. Obviously, it's not. When one position is occupied the list box shows the occupied cell index with a Zero. This really shouldn't be there as I want only taken cell indexes to be sent to array and list box. When a second position is occupied 7 zeros are added to the list box. Kinda shows promise as 9 total cells - 2 is 7 but there should be index numbers other than zero to represent the cells that have been occupied.
Also, the indexes shouldn't keep adding on to the dynamic array I need a way to clear the array and resize it back to 0. I tried adding Redim occupied(0) to the top of the code but that didn't seem to work.
I have 12 textboxes named TextBox1 to TextBox12. How can I loop through these textboxes to assign and read the values? I.e.: Dim strTextboxName As String For i As Integer = 1 To 12 strTextboxName = "TextBox" & i TextBox{i}.Text = ...... ????? Next
I would like to add controls like textBox in GridView from code on the fly.
In my project i have one Grid in that i can't decide how many rows and columns are there. so that i just give it DataSource. This working fine. [code]...
I have a dynamically-created GridView which to which I'm attaching a handler using the AddHandler command. The problem is that when I try to refer to sender.rows within that function, it won't do anything because it says that sender.rows.count = 0. I've done enough dynamic form creation that I'm pretty sure that I'm creating the controls, binding them, and adding the handler at the proper points during the page init/load load_complete. Also, I have nearly the exact same code-behind on another form that is not dynamic, and it is able to access the values in the rows.
Considering that the RowCommand event is firing, it's clear that I'm clicking on a row. For some reason it's just not in scope for the handler event. Background: What I really want to do is access the values that are databound to the row. I'm creating a SQLCommand and binding that to the dynamic grid, and I would prefer to talk to the grid's datasource, but that doesn't seem to be possible. Perhaps I'm missing something, but for now it seems that reading the values from the GridView (which I hate doing) is the only thing that works.
In grid there r checkboxes for selecting the records to be updated as soon as checkbox is checked textboxes changes to edit mode. when data is modified and update button is clicked updation should be done to the database.But when update button is clicked its not working.when i checked through breakpoints i m not getting the value for the variable strID.
Protected Sub btnupdate_Click( ByVal sender As Object , ByVal e As System.EventArgs) Handles btnupdate.Click Dim strSql As New StringBuilder( String .Empty) Dim cmdup As New SqlCommand For i As Integer = 0 To GridView1.Rows.Count - 1
I'm just getting back into programming after a few years break and I'm a little clueless as to how I would achieve a small part of a project to get my back into the swing of things.Basically we have a command that sets what the machine does at a certain time of the day. This command has a limit of 8 steps and always has to equal 1440 (24hrs).An example of this command would be: 001*A*480*B*60*C*600*A*300
So this would do.. "A" during 00:00-08:00 "B" till 09:00 "C" till 19:00 "A" till 24:00
I can do the easy part i.e. split them up but I would like someway of dynamically creating another text box if they dont add up to 1440 (I am okay with doing dynamic text boxes and have the findcontrol stuff i guess its just updating the x and y axis on the boxes below so it looks neat?)
I could do 8 textboxes etc but we can have upto 8 of these commands wanting to display on one tab.
I have a variable defined as follows:Dim iRows As List(Of String())I've also been converting that to a list of lists just to make it easier to work with.Dim iRows As List(Of IList(Of String))I would like to bind that list to a GridView using the contents of the nested array/list to dynamically define the columns. I don't know ahead of time how many columns there will be, but I do know that they are all the same throughout the list.
I have been trying to modify the data going into a column by adding spacing to the start of the column before the Row ID, using the level to multiply the amount of spaces.Ie. ID is SVG00098 and is a Level 3 Asset, so it requires 6 spaces before the ID.
I'm creating a dynamic gridview in vb.net using a connected sql database. Everything works fine except 1 thing: when i click the update command, the event just won't fire no matter what I do. the gridview goes into edit mode and the cancel button works fine. This has cost me over 2 days of googling but none of the solutions work. I used breakpoints to check if the code was executed, but it wasn't. If anybody has any experience in this:I believe the problem lies in the addhandler but it doesn't give any errors.I forgot to mention that the sql command was a test and sets the data in that field to 15, now it's 10, it works when i use a normal button or a static gridview.
Public Class WebForm1 Inherits System.Web.UI.Page Dim rowscount As Integer = 2
I could really use some help on this. I have been searching for a solution on the web but haven't been able to find much help.I need to add textboxes to a gridview edit cell, based on the number of rows of text in one of the cells. I have coded the capture of the number of textboxes I need to add.
But I am not sure which Gridview event to add the code, when going into edit mode, to run the loop that will insert additional Textboxes in a specific column of the row selected to edit.
The user sees colA that has text with line vbCRLF's embedded say:
"This is sample text."
"Line2"
"Line3"
My code reads three Carriage Return, Line feeds. So when the user goes into Edit mode I want to provide one text box for each line or more accurately, add two more as one will already exist.
I want to display dataset records in textboxes instead of GridView. I also want to provide next, previous and search option to navigate between records in the dataset. And I also want to provide update and delete buttons to update and delete the current record that is being displayed.
I am using a gridview in my form.aspx page. The textboxes in each row of the gridview are to be populated from a datagrid upon clicking a particular field of the datagrid
I have two textboxes Textbox1 and Textbox2 and 1 gridviewi want my site users may search record either by entering the city name in textbox1 or by entering the country name on textbox2 via gridview
Is there a easy way to input a string or integer into another exe's textbox for example, if i wanted to write into the textbox on the windows calculator '3'.
