thanks for this needed

# re: access the data of Gridview in Rowcommand

More than one way to skin a cat I know; however I use

ctype(sender, GridView).DataKeys(e.CommandArgument)

Because e.CommandArgument is the row index that was clicked; and DataKeys is indexed so you can just look it up :)

I found it to be easier to add a Command Field (specifically a Select) rather than a button field.  You can change the text and make it look like a button if you so wish.  Then you can just use the gridview's SelectedIndexChanged event:

Protected Sub GridView1_SelectedIndexChanged ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.SelectedIndexChanged

   Dim Row As GridViewRow = GridView1.Rows(GridView1.SelectedIndex)

   lblName.Text = Row.Cells(0).Text

   lblAddress.Text = Row.Cells(1).Text

   '...or whatever you want to do with the info.

End Sub

# re: access the data of Gridview in Rowcommand

Dear All,

    I have one problem .In my gridview i want to update the status of one field by clicking linkbutton .For that i used one event i.e RowCommand .And also i have the property allowpaging=true but when i perform paging RowCommand will fired.In that Event i have written come code .

If you know the solution Please send me

# re: access the data of Gridview in Rowcommand

HemaLatha,

Have you wrapped your code in the RowCommand event with a Select statement, If statement, or similar structure so that it only fires your code if your particular commandname is passed?

So you would have something like this:

Select Case e.CommandName

    Case "myfieldscommandname"

          'code to fire would go here

End Select

Doing this should mean that your code will only fire on your command, and not on all commands.

thanks you that was wonderful..

# re: access the data of Gridview in Rowcommand

I have had success using Hannes code and Disturbed Buddha's suggestion. One problem I am encountering on both is, If I use the gridviews allowsorting where the rows can be sorted using the column headings, when clicking the Select button on a particular row after sorting, the key that is returned is the row key of the way the gridview looked with originally displayed.  So upon initial display, let's say row 2, cell 2 had a value of '6' and after sorting on one of the columns visually row 2 cell 2 now contains a '12', when I click the select command or button, row 2 cell 2 still holds a '6' rather than a '12'.

Has any one had this problem? Thanks

Thanks.Your article is very nice.

# re: access the data of Gridview in Rowcommand

I have a problems with that. When I am editting the ButtonField.Text, the fields isn't clickable anymore !

<asp:ButtonField meta:resourcekey="Document" CommandName="ProjetStatusDetails"

HeaderText="Document(s)" ButtonType="Link">

</asp:ButtonField>

So this was my ButtonField. Now I assing a text to him during the RowDataBound Event.

gvProjetDocument as my GridView

"NbrDocument" as my Number of document for a specific Project (I perform a count in the SQL Query)

Protected Sub gvProjetDocument_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvProjet.RowDataBound

       If e.Row.RowIndex >= 0 Then

           e.Row().Cells(ColonneName.Document).Text = GetLocalResourceObject("Document") & " (" & CType(gvProjet.DataSource, Data.DataTable).Rows(e.Row.RowIndex).Item("NbrDocument") & ")"

       End If

   End Sub

Like you see I don't change the text of the row -1 because it's the Header row title.

So everything works fine when I look at the Output I have something like : "Details (3)"

But this link isn't clikable anymore....

Anyone have an idea ?

# re: access the data of Gridview in Rowcommand

Ok I found what was the problem.

When I was editting the .Text property, I think he replace all value in my <td></td> output for the text I placed there.

So I use that to solve the problem.

       If e.Row.RowIndex >= 0 Then

           CType(e.Row.Cells(ColonneName.Document).Controls.Item(0), LinkButton).Text = GetLocalResourceObject("Document") & " (" & CType(gvProjet.DataSource, Data.DataTable).Rows(e.Row.RowIndex).Item("NbrDocument") & ")"

       End If

# re: access the data of Gridview in Rowcommand

This comment is in response to using a template column.  On solution would be in the row command you could find the control by ID in the selected row.  Below is an example of code that would go in the rowcommand event.

Dim row As GridViewRow = CType(e.CommandSource, GridView).Rows(e.CommandArgument)

Dim ckbTemp As CheckBox = CType(row.FindControl("ckbCheckboxID"), CheckBox)

Dim lblTemp As Label = CType(row.FindControl("lblLabelID"), Label)

If e.CommandName = "EDIT" Then

lblLabelOnPage.Text = lblTemp.Text

End if
