VS 2008 Call KeyUp Event From MouseUp Event For A Textbox?

Aug 16, 2010

In VB6 we had a code inside textBox_MouseUp to call textBox_KeyUp(-1, 0) and the signature of KeyUp was
Private Sub textBox_KeyUp(ByRef KeyCode As Short, ByRef Shift As Short) Handles textBox.KeyUp

Now when I migrate to .NET I changed the KeyUp event to Private Sub textBox_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles textBox.KeyUp

How can I do this call textBox_KeyUp(-1,0) now from textBox_MouseUp event?

ADO .NET Equivalent Event To MS ACCESS Form's OnCurrent Event

May 11, 2009

I just want to know if there any equivalent event (ADO. NET VS 2008) event as in MS ACCESS Form's OnCurrent Event.

The reason is I like to make some calculations based on some data bound controls with current datarow data when user clicked a row in DataGridView (or by using bindingNavigator). I've tried with DatagridView's RowEnter event. But some Data bound controls are not yet reflect the data of current datarow when that evet was fired.

In MSDN Help File: It says "RowEnter Event: Occurs when a row receives input focus but before it becomes the current row. "

Asp.net - Populating A Gridview With A Button's Click Event?

Dec 7, 2009

I have a page that has two dropdownlists(one for the locations, and the other for departments), an employee search textbox and a button. On the other page, I have a gridview. Now, what i want to archieve is that when a user types an employee's name in the textbox control, selects a location from the location dropdownlist, and a department from the departments dropdownlist, and click the button(search), the gridview on the other page must show the reqiured information of a SINGLE employee. Only one row must show.

I have created a database for the employees. I know how to do this with the autopostback but i have not tried it using a button's click. NB: the gridview should show only one row of a selected employee. I'm using ASP.NET VB

Update Event Isn't Fired In A Dynamic Gridview?

Feb 20, 2012

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.

Why Doesn't GridView SelectedIndexChanged Event Fire

Dec 2, 2011

I have a GridView which you can click on a row and it should call the SelectedIndexChanged method (which updates another part of the page based on which row was selected). I have done something similar to this before and it worked, but I can't seem to get the SelectedIndexChanged part to be called for some reason.The page is held in a master page which has a form runat="server" tag, and an <asp:ScriptManager> tagI am using e.Row. Attributes.Add("onclick", ClientScript.GetPostBackClientHyperlink(Me.gridMessages, "Select$" & e.Row.RowIndex)) to allow the SelectedIndexChanged to fire by clicking anywhere on the row.To check that the code does work apart from that, I added a CommandField with a SelectButton and that successfully fires, but i would prefer to find a solution without having to use that.[code]

Asp.net - Which Gridview Event To Use To Add Items To The Dropdownlist Used In The Edit Template

Oct 7, 2010

I would like to show different values in a dropdownlist, while editing a gridview, depending on which user is logged in. For example...

The officer would see "Approved by Officer" status.
The director would see "Approved by Director" status

I am trying to add these programatically to a dropdownlist which I have in the edit template of my gridview (approvalsGrid). Here is my code:

Protected Sub ApprovalsGrid_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles ApprovalsGrid.RowUpdating
Dim ApprovalEditDD As DropDownList = CType(ApprovalsGrid.Rows(ApprovalsGrid.EditIndex).FindControl("ApprovalEdit"), DropDownList)

[code]....

I do not get any errors. But get an empty dropdown with no items. Am I using the correct event?

Devexpress Gridview Delete Event Is Firing Multiple Times

Jul 21, 2010

I have a Devexpress Gridview that is linked to a delete, fetch and update stored procedure. The problem I am having is that when I run my program, select a row in the grid and press delete it fires the event multiple times. Specifically it deletes the selected row and then I re-fetch the data so the focus returns to the first row. Which is what I want.

Unfortunately it starts at the beginning of my list and goes down it row by row deleting each row it comes to. It then continues several more times after the rows are deleted. I know this because for each deleted row it asks me if I want to delete it. If I say no then the rows appear to disappear until I manually refresh it after the deleting is done. To make this even more random the second row always reappears after I manually refresh the grid.
