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.

I have a gridview with Action button. When this button is clicked Javascript Confirm Popup will Display, after click on OK the Event have to fire GridviewRowCommand but the strange thing is: when the button is clicked, the rowcommand method is NOT fired! When I place the code on a separate page the event is fired, but when placed inside the tabcontainer for some reason it isnt...
View 7 RepliesI 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 having a hard time figuring this one out, i got a gridview with a sqldatasource that is loading its content, to custom columns a ButtonField and a Boundfield, both are loading in page load event,When i click the ButtonField its trigerring the rowcommand event but i can't figure out how to read the value of the cells wich i need to get for the next step of the program.Here what i got so far :- The aspx

I'm getting the correct index and command name but i cant get the button value or bound field value either.
i am using a grid view . i have added a linkbutton in cell[0]. when clicking on this butoon the below event is working.. actually i tried to get the cell[1].text... but not getting any cell values except cell[0].text... get the cell[1].text value.
protected void grvSchedule_RowCommand(object sender,
GridViewCommandEventArgs e)
{ if (Convert.ToInt32(e.CommandArgument) == 1)
{LinkButton lbt = (LinkButton)e.CommandSource;
GridViewRow grvRow = (GridViewRow)((DataControlFieldCell)lbt.Parent).Parent;
txtTime.Text = grvRow.Cells[0].Text;
//txtTime.Text = grvRow.Cells[1].Text;
mvwApp.ActiveViewIndex = 1;
FillToSavePage();
hfdConsId.Value = ddlConsultant.SelectedValue.Trim();
}
}
get the current selected row in the RowCommand event of a GridView in asp.net. The GridView has a button in an Item Template as shown below,

that I can pass values from GridView to a page. I tried following code but I could
not get the row number.
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,sqldatasource and a link button for delete in the sample code below
When Delete is click the confirmation pops up. When I confirm yes, the rowdeleting event doesn't seem to be firing. I addeed a label to see if the event is firing. To avoid runtime errors I added a dummy but actual sql delete command. Once If I get it to work, I want call a stored procedure to delete the row.
My question is
1. Why is the gridview row deleting event not fired.
[Code]....
I have a very simple page that consisist of an UpdatePanel that contains a gridview. The gridview includes a delete button for each row, which should fire the Delete event. But the event never fires. If I set a breakpoint inside the event handler, it never gets hit and the row does not get deleted. When I say OK on the confirm dialog it just goes back to the page. I tried taking out the confirm button extender

I have an inner gridview called MyInnerGridView and I have operations I need to do in the Row_Updating event but this event is only firing for the last row of the outer gridview. I have pared down the sub to the following and the exception is only thrown when I try to edit an inner gridview record of the last record of the outer gridview.

why this is happening when I edit an inner gridview record of the last row of the outer gridview?
In a .Net 2.0 project, I have a Calendar control within a GridView that has a method set for its OnSelectionChanged event. However, the event never fires and I don't understand why. Here's what's in my aspx page:

I have a problem with my Linkbutton which is not firing the RowCommand of my gridview.
Just for an Idea what I am doing is a follows:
1. WebForm
WebForm hosts UserControl_A.
2. UserControl_A = UpdatePanel + Panels + Gridview1 + CollapsiblePanelExtender
Updatepanel of UserControl_A consists of multiple Panels.
Each Panel consists of a Gridview1.
Upon each Panel expand UserControl_B is loaded.
3. UserControl_B = Details View & a couple of Linkbuttons in GridView2
Upon clicking the Linkbutton, unexpectedly it makes a refresh for the entire UserControl_A.
But it does not fire the RowCommand of its parent GridView2.

I am trying to access column value by using DataBinder.Eval on RowCommand event of Gridview. It always return NOT SET TO ANY INSTANCE error for eveytime. I know how to do this by employing a label control in ItemTemplate, but am trying to find a way to bypass.

all of a sudden my GridView has stopped firing the row update event. Friday I was working on it and was working flawlessly. Now I haven't made any changes to the code and all of a suddent has stopped working (yes rediculously bizarre and have been banging my head all day thinking what the something is wrong with it, excuse my french).
Everyone of those events fire except the update. I click the update button and nothing happens.

It works on Internet Explorer but I have few users who started to use apple's snow leopard and event is not at all firing on those browsers.
I believe some browsers have different JavaScript implementation
I am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.

In my grid veiw Row command sub section i used e.command argument. But it always return empty string like ""my code is like this........

Dim rowindex As Integer = Convert.ToInt32(e.CommandArgument)
End Sub
I want row index to do type cast my textbox inside my grid item template.

Now I am not able to understand why the OnRowCommand event is not firing. Nothing is happening on clicking the button in gridview.
i have some textboxes in my parent page and a search button. when the search button is clicked, my modalpopup pops up. after chosing (clicking on the select button of the row) an entry from a gridview within my modalpopup (each row in the gridview has a buttonField), the rowCommand_Event fires... within this event i try to set the .Text property of some textboxes within the page containing my modalpopupExtender... i get no exceptions, but the textboxes are not set...

e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#FFC080';")
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='';")
