Put GridView in Edit Mode Programmatically

Jun 22, 2006 11:20 AM|LINK

Hello:

I am developing an extended GridView.

I have added a new event which is double click, and that event will be fired in a CallBack, everything now works fine, except that, I need to set the Grid in the Edit Mode. The method below is called from the RaiseCallBackEvent method, it is setting the SelectedIndex right, but the problem is that, the Row is not set in the EditMode.

Am I missing anything?

protected virtual void OnRowDoubleClick(RowDoubleClickEventArgs e)
        {
            // Set a selection in the Grid
            int rowIndex = e.GridViewRow.RowIndex;


            // Select the row
            this.SelectedIndex = rowIndex;


            // Set the edit row
            this.EditIndex = rowIndex;


            // Change the row state
            this.Rows[rowIndex].RowState = DataControlRowState.Edit;


            RowDoubleClickEventHandler handler1 = (RowDoubleClickEventHandler)base.Events[xGrid.EventRowDoubleClick];
            if (handler1 != null)
            {
                handler1(this, e);
            }
        }

Thanks a lot.

Once you set the EditIndex, I believe you must rebind your GridView to the DataSource.

Thanks, Ed

Well, I added the Grid.Databind() and now the row is being shown in the Edit Mode. But, when I click Update linkbutton, it just posts back, I have to click it again to update the data. Any ideas?

When you click the Update button, are you getting the RowUpdating event? What shows up in your RowCommand event?

Hello Polita: How are you? Hope all is fine.

I was away from my home for one week, now I am back!

I am attaching the code for you, you have mainly two properties till now, one to EnableRowClick and one to EnableEditCallback, the second when you double click, the row is in editable mode, but when I click update nothing happens, no update is done.

Because the code is too big, I will be sending it to you by email!

Thanks a lot.

Did you figure out what was the issue? I am having the same issue. I have to click edit twice, to get it in edit mode and likewise to update.

Did anyone ever find the solution to the edit button having to be clicked twice to get into edit mode?

Did anyone try handling the RowUpdating event?

Yes. I got RowUpdating event working correctly with just one click. But I still need two clicks on Edit button to get the control in edit mode. Dont know why.

protected void gvabc_RowUpdating(object sender, GridViewUpdateEventArgs e)

{

try

{

_a= Convert.ToInt32(((Label)gvabc.Rows[gvabc.EditIndex].Cells[0].Controls[1]).Text.Trim().ToString());

_b= ((TextBox)gvabc.Rows[gvabc.EditIndex].Cells[1].Controls[1]).Text.Trim().ToString();

_c= ((TextBox)gvabc.Rows[gvabc.EditIndex].Cells[2].Controls[1]).Text.Trim().ToString();

_d= ((TextBox)gvabc.Rows[gvabc.EditIndex].Cells[3].Controls[1]).Text.Trim().ToString();

_e= Convert.ToDecimal(((TextBox)gvabc.Rows[gvabc.EditIndex].Cells[4].Controls[1]).Text.Trim().ToString());

_f= Convert.ToDecimal(((TextBox)gvabc.Rows[gvabc.EditIndex].Cells[5].Controls[1]).Text.Trim().ToString());

_g= Convert.ToDecimal(((TextBox)gvabc.Rows[gvabc.EditIndex].Cells[6].Controls[1]).Text.Trim().ToString());

_h= Convert.ToDecimal(((TextBox)gvabc.Rows[gvabc.EditIndex].Cells[7].Controls[1]).Text.Trim().ToString());

_abcPresenter.UpdateformDetail();

gvabc.EditIndex = -1;

BindGrid();

catch(Exception ex)

{

throw new Exception(ex.Message);

}

}

Note: I have changed the variable names to protect the identity.

It sounds to me like an extraneous DataBind() is getting called. Look for calls to DataBind() in PageLoad that aren't in if(!PostBack) blocks.
