DataGridView On A Form That Is Being Populated From A SQL Table Dataset By Giving Criteria From A Previous Form?
Apr 8, 2009
I have a DataGridView on a form that is being populated from a SQL table dataset by giving criteria from a previous form. I have 6 columns in the dataset, of which the last column should be combo box column containing items "Done" and "Pending". How do I make this bound column to a combo box column and display the value as well as the alternate item too in the combo box?
I have a large form that is set up from master-detail datasets in Visual Studio 2008.I havene master table with a large amount of detail tables. Several of the detail tables also have detail tables linked.Now I need to add a master table that sits on top of my existing master table making it a detail table.
I have three tables, the extremely simplified versions of which are:
Practitioners: practitioner_id :: int name :: nvarchar
Insurances: insurance_id :: int name :: nvarchar
InsuranceLink: practitioner_id :: int insurance_id :: int
So, the practitioner table contains a list of practitioners, the insurance table contains a list of insurances, and the link table represents which practitioner supports which insurance. Now, I need to create a view which can display the information like this:
ViewTable: practitioner_id :: int practitioner_name :: nvarchar insurance_1 :: bit insurance_2 :: bit ..... insurance_100 :: bit
In other words, the columns in the view are the ID and name of the practitioner, and every insurance that exists in Insurances (with the insurance name as the column name (there is an enforced condition that insurance names are unique)). The cells in the insurance columns will indicate if that practitioner supports that insurance. Or better yet, is it possible to use an excel-style pivot table on a DataSet in a VB.NET form?
Dim Type As String = frmFrontEnd.cmbModel.SelectedText.Substring(0, 4) cmbType.SelectedText = Type
i would like to take a selected aircraft type from a previous form and put it into the form i am working on at the moment, but i want to edit the string so it only has 4 characters.I thought the above line would do it but apparently not. the error is to do with the length.An example:the model in 'the other' combobox is A330-200/-300 and i would like to put A330 into the new combobox cmbType in the above code.
I have written some functions that I have in a module. In one of the functions I would like to update a table that is in a dataset. I would like to do this with this function and not from a form class where the table could be bound. I need to call the function from various places in the application.
I am working on VB.Net. I have a sub form with a datagridview, that is being loaded with the criteria taken from another form. Hence this form is called with parameters. Here is the code that calls the sub form.
[code]...
where ds is the dataset to fill the datagridview and rb is the string from a radio button on this form.
Here is the code in the sub form.
[code]...
Now, I need to refresh this sub form every -- minutes, depending on how the user wants it to be. For this I have given a NumericUpDown control to select the mins. All this works fine. But how do I refresh the dataset and the datagridview?
I have created a windows form that has a datagridview linked to a DB from a DataSet. i have draged the fields from the Data Sources navigation window to various controls on my form. all works well. then i tried building my program. my first ever build. i don't know what is wrong or what i have to do. when i try to run my exe, i have the following message. can someone help me fix this?
i deleted my previous start up form to be replaced by another one but each time i launch the application,the deleted start up form is still displayed.i dont know from where this deleted start up form is being loaded.
Imports System.Data Imports System.Data.OleDb Public Class Form1 Dim con As OleDbConnection Dim cmd As OleDbCommand
[CODE]...............
The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
I have a Windows application form. Directly on the form I have a lable ("Customer Names"), a ComboBox (pulling actually names from a database) , and a Buton to add a customer to the database if i choose. Additionally I have ControlTab(3 tabs) that has "fields" and its own Buttons to insert data into a different table. The first 2 tabs have textBoxes, which are completely functional, but the 3rd tab has a "DataGridView"
My form contains a datagrid and a checked listbox. The listbox is populated on the form_load event. There's a function called when the datagrid's SelectionChanged event is triggered that modifies the checkmarks in the listbox. It all works fine when I manually click on any item in the datagrid.
However, the very first time the form runs, the checkmarks are not affected, even though the first item in the datagrid appears selected. I discovered that this is because the actual listbox is not yet populated on the form at the time the very first SelectionChanged event is triggered. So when the function tries setting the checkboxes, it doesn't get anywhere, since it doesn't see any items in the listbox.
Somehow the datagrid is getting populated, even before the form_load event is triggered. I need the listbox to be populated before the datagrid is populated, but I have no idea how to control this.
[code]the main piece deals with the binding source filter. I've tried or/and. i tried to include that both codes in the string. i don't know what to do again i know you would recommend SQL but i don't know how to use that yet, so could you please recommend some bindingsourcefilter code to assist please. Its for a School project the search window looks like the attached picture
I have two forms....Mainform is filled with controls that are databound to a datasource.....then I have a child form that is used to edit data from parent form.......the data that is displayed on the child form uses the Filter() method of the binding source to display data only for the customer selected......
The child form has the standard OK and CANCEL buttons set up as dialog result.......after I edit the content in child form, the changes are displayed on the child form correctly......but when closing the child form and going back to the parent form the changes dont appear there unless I restart the application.....I also tried adding the tableadapter.update/fill method in the 'OK' dialog result event handler and it still doesnt work......
How can I make the changes take effect on the parent form without restarting the application?
(THQ836721='Yes' and BRQ836716='Yes') or (BRQ836717='Yes') and (THQ836728='Yes' and BRQ836756='Yes') or (BRQ836117='Yes') and (SYSQ123='No')
I need a Reg Ex to get the numbers after THQ,BRQ and SYSQMy string may smaller or shorter or may have any times of this THQ,BRQ or SYSQ.form a Reg eXpression to get the numbers .The length of numbers may vary I am using VB.Net in VS2008?
how can I put this idea in code to say: if TheLastFormVisitedIsFormCustomers then
CurrentForm.myTextBox.Focus End If
In simple english. How can I retrieve the name of the last form visited in code and give focus to a textbox control depending on the last form visisted.
Im using visual studio 2008, i have created 2 webforms frm1 and frm2,,,i have a button in frm1 which i would like it to onclick populate textbox values to the other form(frm2)...
Ok so basically heres what i need to do: Extract text from the webpage that meets a certain criteria. There will be a ton of these on 1 page and i would like to add them to a rich textbox on sperate lines.
I know that it needs to be in a loop and its needs to Parse the wepage(Dim web1 As String = Me.WebBrowser1.Document.Body.InnerText)
The criteria is: Starts with 1 to 4(random) integers, Followed by "my" then 13(random) numbers and letters. Or if it starts with "167my" + 6(random) number and letters.
Edit: Also im going to try to make it loop through a list of webpages to do this.
I have 2 forms right now Form1 and Form2 the default setting start up is Form2. Inside Form 2 there was a button that will release the Form1 button using Form1.Show().[code]...
I need some guidance on the best way to proceed with searching a file content. I have a large file (see attachment) that is in text form, some of these files could be upto 50 times as big, therefore creating a huge file. These files contain information that is produced from another application and therefore I am unable to change the format of the file.
I have a menustrip, in which i have put a BACK option so that the user can go back directly from where he came to the current form, as there are many form which leads to the that particular form.
I have this code I use on my form which has worked fine up until now I need to add another form to my project but the text from form 1 gets overwritten when form 2 gets added How can I append my data without overwriting the previous form.
Dim sfd As New SaveFileDialog sfd.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*" sfd.ShowDialog() Dim writer As New System.IO.StreamWriter(sfd.FileName) writer.Write(RichTextBox1.Text [Code] .....
I have a total of 4 forms, the first three of which have information that is totaled on each of those three forms respectively .I'm trying to figure out the best way to set up a final page where each total amount from the first 3 forms will end up on the 4th form so that the sum of the totals from the first 3 forms will add up, and then so I can add 7% on for taxes on this project.I am using both radio buttons and check boxes for the first three forms (and I'm not certain if this would be an important factor).I had been looking at creating a listbox, but I'm not sure if it would be possibly to get the previous totals to show up correctly there, so I suppose I'm just looking for a way to have the "products" from the first three froms show up in a list along with their prices, and then be able to add on the tax and total them all together.
I am creating a custom design for printing (RDLC)Is this possible to populate my rdlc from pre populated Dataset?I am populating my dataset like this
Private Sub populateExam() Dim daClients As New SqlDataAdapter Dim dsClients As New DataSet
[code]....
My Dataset hold only 1 record from my database.I need to pass that record into my cutomize page for printing.This is my layout. the red rectangle is the place for the values.
I have several forms that are "reused," or vistited more than once per each time in the whole program. In VB6, using Form.Show() would show the form in its original state (the state is was when created in the designer). After closing this form (Unload Me), showing it again would still show the form in its original state.
I am coding in VB.NET 2008, and noticed that when I reopen a form I had closed during a session using my program, the form is in the state it was when I closed it (labels and listboxes filled with data), and not in its original state. I currently have the Form.Closing event filled with code to clear all of the controls, but I think that there must be a better way to "clear" or "reset" the form.
I have two forms, forms a and b. Each form has a combo box. The user selects an item from form A's combo box and saves their selection to a database by pressing a button. How can I display their combo box selection from form A in form B's combo box on form B's form_load event?
