Forms Data Controls :: Way To Get Gridview Name From RowCommand GridViewCommandEventArgs
Jul 28, 2010
I have several Gridviews that display data from the same table. They are separate for visual effect (Different characteristics). If I select on an item from any grid they can all execute the same code (Show Details).I'm using a row command GridViewCommandEventArgs.Is it possible/How can you get the gridview name from the row command so that I can use just one subroutine.
Sub GV_RowCommand(ByVal sender
As
Object, ByVal e
As GridViewCommandEventArgs)
If e.CommandName = "select" Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim row As GridViewRow = ????.Rows(index)

I have a gridview and I have a link button that fires the onrowcommand event. In the method I have
protected void SelectCreditCard(object sender, GridViewCommandEventArgs e)
{
int index = Convert.ToInt32(e.CommandArgument);
}
But I get the error input string in incorrect format.

I have one button and gridview.
The button is located at the outside of gridview.
By clicking the button, I want to trigger the RowCommand event in that grid.
Obviously, I know that I can create same function to run it in that button to achieve samething in the RowCommand event.
However, I would like to know that techinically, I can simply trigger the RowCommand event from outside of GridView.

I'm trying to fire the RowCommand event on a DataGrid control. I've previously done that, but not in this precise case.
Actually I'm working on someone else code so I can't really change the structure of his page excepted if it's really necessary.
The code of the page is heavy, so I've summarized the problem in a small project and the page behaves the same way too.
Basically I have a GridView which I bind to a DataSet. According to those data, I sometimes need to add, at the end of a row, a "Details" button (a LinkButton).
By pushing this button, I want to show a second GridView containing those details.
Let's add to this that the columns number of the first GridView is variable, those LinkButton need to be added dynamically.
The first GridView is generated without any problem and when my mouse is over one of the LinkButton, I can see that the link is something like "javascript:__doPostBack('dataGridView$ctl02$lnkDetail','')". When I click on this link and debug step by step : Page_Init, Page_Load, OnPrerender, RowDataBound but no RowCommand, and I don't know why!
In the exemple, I've explicitly set the EnableViewState to true from what I've read here and there, but nothing's changed.

And the code of my .aspx :

It has to do with the RowCommand 'Cancel'. When clicking on my Edit button for a row, the GridView puts the row into edit mode without a problem (I have no code for the Edit command, I let the control do everything).
Once in Edit mode, if I click the Cancel button (again, I have no code handline this RowCommand, I let the control handle it (like i do with many other GridViews)) I get the following exception:
"System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

GridViewRow row = (GridViewRow)(((Repeater)e.CommandSource).NamingContainer);
Repeater _rpt1 = row.Cells[8].FindControl("rptReg") as Repeater;

actually i am trying to delete the row from the gridview control and when the user click on it and i am grabbing the mulitple ids and passing to SP and update the table and `databind the gridview`
GridViewRow row = gv.SelectedRow;
Repeater _rpt = gv.Rows[e.RowIndex].Cells[8].FindControl("rptReg") as Repeater;
Repeater _rpt1 = gv.Rows[e.RowIndex].Cells[9].FindControl("rptVisitor") as Repeater;
foreach (RepeaterItem item in _rpt.Items)
{
TextBox _txt = item.FindControl("txtId") as TextBox;
TextBox _txt1 = item.FindControl("txtName") as TextBox;
//update db

I have two gridviews tied to a SQL backend both being displayed within an update panel. Both the gridviews have a linkbutton connected to a rowcommand. When clicking on one of the rowcommand link buttons, the database is updated and the update panel is refreshed (moving the record to be displayed in the other gridview in the panel). However, when the rowcommand from the other gridview is clicked, the code is run and the database is updated, but the update panel is NOT refreshed.I have debugged it and have found that the code is running as expected. It fires off the function and updates the database. If I click away from the page and then go back, it does show the data in the proper gridviews, so I know that the code is working.

I have a gridview with a ButtonField. When I leave the button type as the default LinkButton, clicking that button fires the RowCommand and everything works as expected. As soon as I change the button type to ImageButton and assign an ImageUrl, clicking that button does not fire the RowCommand.

I already implemented the dynamic templatefield which will re-created in every postback. Everytime I make a postback in the page I see no problem but when I click my imagebutton inside the gridview then the dynamic templatefield disappear.
To double check if it is really gone at all I just select the second page of the gridview using my customize paging using dropdownlist outside the gridview and the templatefield with its correct data reappear again.
I already put a variable inside the rowcommand to see if the number of columns are the same with the number of columns the gridview render together with the dynamic templatefield during debugging and it is there but cannot render that templatefield in the client.

I'm trying to retreive values entered by users in the textboxes in the footer of the gridview and insert these values into another sql table.My code is as follows :-
protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)
{
if(e.CommandName.Equals("addnew"))
{
TextBox t1 = (TextBox)GridView2.FooterRow.FindControl("tfrm");
string frm = t1.Text;
TextBox t2 = (TextBox)GridView2.FooterRow.FindControl("tsub");
string sub = t2.Text;
string cmd = "insert into suggestions values('" + frm + "','" + sub + "','c','c')";
con.Open();
SqlCommand com = new SqlCommand(cmd,con);
int a = com.ExecuteNonQuery();
GridView2.DataBind();
con.Close();
}
}
But the strings 'frm' and 'sub' returns null values.

I have a GridView attached to an ObjectDataSource (returning a DataTable) in a UserControl. The code is really simple. Data comes down fine when the page is first rendered. When I click on Select or Delete (inside TemplateFields), RowCommand is supposed to fire but it doesn't, the page goes straight to Page_Load. I literally have 0 other event handlers that are set on this control and everything else in the codebehind shouldn't even fire if it's a postback. Also on postback, the Select and Delete buttons disappear. It looks like the TemplateFields are still there but they're empty. The data fields (all of two columns) post back fine.
