Findcontrol in gridview rowupdating event singletreff Freiburg im Breisgau
How do I access this control in the Grid View_Row Updating event in order to save the uploaded file to the file system? Thanks I have applied this method for using the File Upload but when the code behind runs the . You can use the Row Index property to get the row you are editing from the Grid View’s Rows collection.
The fact that it is inside Edit Item Template means you are editing so the most likely place is at Row Updating which is the final destination before the grid commits the changes to the database. To get the instance of the control you can hook up to the Grid View’s Row Updating event.
The following is an example where the File Upload control is added to the Grid View: HI Yasserzaid, I still have the issue of once the user clicks the edit row the fileupload control comes up with a blank textbox. Like this: Private Sub update Grid(By Val sender As Object, By Val e As System.
If the user doesn't enter a filename and then clicks update the old filename is blanked out.
I would like to keep the old value if the user doesn't enter a new value.
I've tried not updating the parameter with an if then like this: If f File Attachment.
Visual Studio allows developers to quickly put together a Web Forms page simply using drag and drop options from the Visual Studio editor.
Binding form controls is mostly a simple matter of attaching a Data Source and setting your controls to reference the correct field in the Data Source.
Today I was working on getting a row of the Grid View control to save the contents of a Drop Down List, and needed to add some custom code to set values passed to the Sql Data Source control on the update event. Then within the new method one can access controls within the Grid View row being edited by referencing the Row Index attribute of the Grid View’s Rows collection. Find Control("ddl Service Level List"), Drop Down List) Dim lbl Support Date As Label = CType(GVSupport Info. So for example to reference a Drop Down List within the Grid View Row, use the syntax: Basically this is quite straightforward once one knows the syntax for referencing a control within a Grid View Row. Grid View Update Event Args) Dim lbl Service Level As Drop Down List = CType(GVSupport Info. I found that simple data binding of my Drop Down List in my Grid View to my Sql Data Source was not going to be enough. I would need to set values passed to the Sql Data Source control on the update event, and as part of this I would need to reference the controls contained in the row being updated.
