Before any jumps in and says, Why dont you just use a gridview, i have my reasons not to use it.I trying to dynamically create a table and then populate the cells via a linq object.
Good news, i can dynamically create the table and the cells.
Dim numrows As Integer = MyActions.Count()
Dim numcells As Integer = 5
[code].....
As a bonus to the project I'm currently working on, the people would like it if I could change the background color of individual table cells depending on what their value is. So in the RadGrid_ItemDataBound event handler I have, I'm trying to set the BackColor of the cell if the cell's text equals a certain value from a dataset in my database. My current code is like so:
[Code]...
I have the following table row on my .aspx page.
Initial Requirements:
<ItemTemplate>
<td valign="bottom" id="ReqStatus" runat="server" style="background-color: Gray">
<%#ReqStatus(CType(CType(Container.DataItem, System.Data.DataRowView).Row, DataSet1.DataTable1Row))%>
[Code]....
I can change the color of the return value based on conditional statements but cannot figure out the correct syntax to change the table cell back ground. My attempt is commented out.
How do I correctly declare the table cell? Findcontrol must not be the correct way.
I currently have this code to create an asp table [code]where PH is my placeholder for the table to appear in.This code creates a 1 celled table how do i get it to create multiple rows and cells?
View 9 RepliesI am working on a CMS system for my business, and need to be able to generate notifications dynamically into a control panel. Please note, I am using .NET 2.0, coding with VB and my data is all held on a MySQL database.This is pretty simple for most aspects, but as the whole thing is dynamic some things are proving more difficult.I have a set of tags which are dynamically generated with a repeater as follows:
<asp:Repeater runat="server" ID="locationRepeater">
<ItemTemplate>
<p id='locationNotification' title="<%# Container.DataItem %>" runat='server'>
COUNT DATA NEEDS TO GO HERE
</p>
[Code]...
The data is really, really, simple, all I need to be able to do is query a table on my MySQL database for COUNT of ID WHERE locationName = Container.DataItem during each loop of the repeater... but I don't know how to do this.I'm thinking maybe I have to do this first, create a table in memory somehow, but I am afraid I have no idea how to achieve this.
Has anyone got any examples of a similar thing, it's kind of binding to a repeater from two datasources... each task is very simple, but I don't know how to put it all together!
I am working on a weboage that will display questions and answers (maybe 5 at one time, maybe 7 at another time) returned from a database table. The questions will each be displayed in a div and the related answers displayed in another div. The question will have an icon "Show Answer / Hide Answer"
How can I go about creating a div and then populating it with values from a table?
I have this code.
Code:
Public Class Form1
Dim NPB As Button
Dim x As Integer

As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?
I have a vb.net website with a gridview that currently has exam questions displaying vertically in each row like this:
Name question answer

Name question1 question2 question3

This makes it more readable since each user is only listed once.I would like to stick with a gridview instead of rewriting all my code.I am actually binding my data to the gridview via some other programmers class. I am using LINQ like this:

I have a large form of 16 rows, and 5 columns of comboboxes. Three rows will be filled with the same information as a list of about 20 items. Two rows contain the same information of only 5 items.

I have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.
Private Sub GridViewParameters_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewParameters.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then[code].....
Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?
I am trying to create a basic quoting tool but got stuck on how to clear and change the item collection from within a combobox for a datagrid.What we have is a list of 4 columns like a. Device b.TypeofService c.State d.Price Inside a sql database. Data is also structure like above as well.
I have a datagridview where the user will populate a,b,c and the price will be display and a total at the end. However a,b, and c aren't related in my current application. The combobox will show all possible dinstinct values for each column.
This works fine but I want to refine the application to only show the values of b. which are in the database after the user select the value for a. I have tried searching on how to do this as I assume to the Contry/State/City situation but could not find anything for a datagridview control in VB.NET.
Can anyone point me in the right direction? If I cannot do this dynamically from within a datagridview I was thinking of maybe creating three combo box outside and having it populating the datagridview afterwards but it wouldn't be as nice.
I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.

I am building a form that will eventually list a group of functions on the left. If you drag a function onto the form, it will create a listbox and a label at the loction you dropped it to. If you drag a function into a listbox, it will add that function as a listbox item. I have this working kind of. The problem is that once I create a new listbox, I am no longer able to add items to the previous ones. Here is my code:
Public Class Form1

I am trying to populate a dictionary with objects created from data in a recordset, but am having difficulty with VB's object referencing. I am very new to VB. Pseudo code of what I am trying to do:
dim dict as Dictionary
rs = getRecordSet
while rs.moveNext
set myObj = new MyClass
myObj.properties = rs.relevantFields
dict.add myObj.getUniqueKey, myObj
wend
However, all 'objects' in the dictionary are actually references to the most recently created (and thus last) object in the dictionary. I know why what I am doing above is not working, but I don't know the correct way to do it so that each element in the dictionary is it's own object.
I'm writing a scheduling program that queries a MySQL database for today's appointments and uses a Table Layout Panel with employees on the top and times on the left to display the schedule. I am trying to add another table ontop of that table for each appointment and set the rowspan of that dynamic table to occupy the time slot of that appointment from start to finish.ll the appointments appear in the dynamic table and each dynamic table appears in the appropriate starting positions in the main table. When you are designing GUI's and put a Table within a table, you get a RowSpan and ColumnSpan option for that inner table. The problem I'm having is the dynamic tables are not giving me a RowSpan option, which I believe is because it was created using code and doesn't know that it's inside another table.Here is part of the code... This code is inside loops for each appointment of each employee
sqlCustomer = MyReader.GetValue(0).ToString()
sqlCompany = MyReader.GetValue(1).ToString()
sqlProblem = MyReader.GetValue(2).ToString()

I'm working in VB 2008 Express.
I have an MS Access DB with a Table setup with the columns that I need.
I have it linked into a form, with the requisite BindingSource, TableAdapter, BindingNavigator, etc.
On the form, I also have several textboxes linked back to the table. I can populate the table via the + (add new) button in the BindingNavigator and then filling in the textboxes (and saving of course).
Is there a way that I can put a button on the form and populate the table automatically? I want to do this via a textbox to control the number of records added - that way, I can put in an 8 and have 8 blank records added to the table via this one click (and don't have to enter the default info in for the 8 records one at a time).
I've attempted to do this by calling the BindingNavigatorAddNewItem_Click subroutine, filling in the textboxes and then calling MapBindingNavigatorSaveItem_Click subroutine, but this does not work.
I am using a string builder to set up an html table row by row so that it can be emailed. I currently gather my information from the database using a data reader and while dataReader.read, I use stringbuilder.Append to add each cell value to the table.The issue is that after about 200 rows, the html breaks and displays a cell value above the table in the email. I have tried changing the cell padding, but this was not successful.

View 2 RepliesI'm having some problems trying to input records into a relational database. The design is really simple but I'm running into a wall when it comes to having the foreign key from my child table autopopulate the primary key from the parent table. I've made the connections in Access and from what I understood, so long as I committed a transaction, the child table would populate the primary key from the parent table. This is not happening.
my question is: is there a method that would do what I'm looking for? or am I cornered into using @@IDENTITY and manually inserting the primary key into the child table?
I've tried using datasets and data adapters and created a datarelation within the dataset, but it is still not doing what I need. everything I've tried thus far has allowed me to insert records into multiple tables, but won't relate them because of the missing primary key in the child table.
I have 2 queries. One is populating a dataset that populates the dropdownlist and the other populates rest of the textboxes of a table row. i want to know how can i fill the entire dropdownlist and then make selectedvalue the value from the other query? e.g -
dataset query = select hobby from hobbies
other query - select name, dob, address, hobby from employee
now the table looks like this -
Name DOB Address Hobby
Sam 01/10/1988 111 main st Dropdownlist(n number of records)
Now in the dropdownlist I want all the hobbies populated with the hobby in the employee table to be the selected value.
