Forms Data Controls :: Raise Click Event Of A Linkbutton Inside A Template Field That Was Created Programmatically
Jan 28, 2011
I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?
Code:

I have a LinkButton inside a GridView (via an TemplateField). No matter what I try, the LinkButton will not invoke its event handler. I have tried both traditional event handler ("OnClick")A OnRowCommand event handler at the GridView level.In both cases, I've debugged and it doesn't even catch the event handler.
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton Text="Cancel" ID="DeleteButton" CausesValidation="false" OnClick="CancelThis" runat="server" />

I would like to call a method and pass a value to it on a link button autogenerated from the database in a templatefield inside a datagrid. I don't know much about delegates
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
..
((LinkButton)e.Row.Cells[(int)eMessage.TitleColumn].FindControl("btnMessageTitle")).Click += new EventHandler(delegate { viewSelectedMessage(this, 35); });
}
void viewSelectedMessage(object sender, int messageID)
{
lblTest.Text = messageID;
}
running the website and viewing the page source, I have realised that there is an OnClick event created for the linkbutton, however, this may be generated anyways. By running my solution using VS debugging, I can see that my method won't fire by clicking any of thos generated linkbuttons.

I have a repeater control and in its footer temlate is a button (or 2 in the example) and I want to catch its click event but seem to not be able to.
I tried in the repeater itemcommand event and also I tried defining a subprocedure for the 'occlick' event but neither works..

I am adding numerical page links for paging of a repeater. I have used on of the numerical paging samples as my base. It works fine if I have less pages than my maximum total links. Eg if I have 11 pages, but only showing page 1-10 plus a next for the 11th, I get an error about duplicate control ids. I changed my control id to use a Guid in the string to keep it unque, after making this change the event handler never fires
private LinkButton createButton(string title, int index)
LinkButton lnk = new LinkButton();
//lnk.ID = System.Guid.NewGuid().ToString("N") + "_" + index.ToString();//Event does not fire if I set ID with Guid

I have a gridview control set up like so:
[Code]....
I am using an IComparer to do the sorting of the gridview and binding it to a list of objects. It used to be that the linkbutton in the first template field was being done like this:
[Code]....
The sorting worked just fine when it was like this, but I would prefer not to use a querystring value. The problem with using the linkbutton is that the sorting appears to work (there are only two rows in my test case and they change places), but when the linkbutton is clicked on it is in the same order before the sort took place. After each sort the gridview's datasource is reset to the newly sorted list of objects and the databind method is called.

I have an application that I would like to be able to allow the user to modify multiple characteristics of each record within a datagrid.
Most characteristics require data to be entered in a text box but some a check box would be more appropriate.
My question is does a gridview column need to have all the same item template controls? or could I read from the database the control type and dynamically alter the template control for each row as it loads?

I have created a master page for website layout in my project. I have used a linkbutton control to trigger between Login/Logout functionality but when I click on this control the underlying click event handler is not being executed anyway.When I click on this control, the page pointed by its PostBackUrl property is open which should probably occure after its click event hander have been executed.

and the LinkButton Control is

I have written some code to dynamically generate template columns for gridview which works well. However, each cell in the gridview has to be a linkbutton, which when clicked does a db update and redirects to a specific url with some parameters in it.
I have attached a click event handler to the linkbutton in the InstantiateIn method but the event does not seem to fire.
//Dynamically creating the Grid
protected void btnAnalyze_Click(object sender, EventArgs e)

The LinkButton on click event automatically does what I think is called a postback. What line of code do I need to use to invoke this event?

I am working on an ASP.NET web application using .net 4.0 and VS2010.
I have a GridView and I am appending a row at the bottom to allow users to input data for "Adding" a new record.
The ONLY way I have found for this to work is to do this in the RowDataBound event of the grid. I can check to see if it is about to process the footer row then I know I am at the bottom and can insert this new row.
The row I am inserting contains a couple of TextBoxes and a LinkButton for the "Add" link.
If I just drop a LinkButton on my form and hook up the click event and I click the link button then the first thing that fires is the Page_Load event then my click event. However what is happening when I click the link button that was dynamically added to the GridView is the Page_Load event fires but the click event never does.
I have read 1000 threads saying to try to create the controls in the preinit() or some other event. In my case I can't. Or else someone would have to explain how to add the row to the bottom of the databound GridView.
Here is my code: (I removed creating the Textboxes because that is not part of the problem.

I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.
There is a submit button on the page as well.(this is not in a template column in the gridview)
what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.
Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.

I've created a databound gridview inside the gridview's RowDataBound I use the RowSpan property to merge cells. The grid ends up looking like this for example....
Data Data Data Button
Data Data Button
Data Data Data Button
Data Data Button
Data Data Data Button
The button is generated using a Template Field and is a standard ASP:Button. If I click a button in an unmerged row everything works as expected. If I click a button in a merged row...the sender object on the command comes back as null and no matter what I try I can't seem to fix it or get a reference to the button.
sender.CommandArgument
for example returns and empty string.

Using a listview control for the first time... I need a button for each item, and of course I need to handle the click event for the buttons... upon clicking a particular button I of course need to know which item the button is associated with so the appropriate action can be taken...
In VS, I can't select the button and see my list of available events in the properties window like is normally done for controls outside of templates like this... what do I need to do?
