i am able to find textbox in gridview in RowDataBound event but how to perform action on click event on textbox for individual row
I am creating a button dynamically in my code and attaching a click event to it. However I have to prevent people to click it while there is a process going on. So when it is clicked once, it should be disabled and when the process ends it should be enabled. How can I do that?

how to handle click event of linkbutton in gridview in asp.net
View 2 RepliesThe 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?
View 3 RepliesI 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 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 am new to asp.net and im doing a web page in which i have a teeview in my detailview.I add nodes to treeview in detailview itemscreated event and its working fine ,adding nodes accordingly except when i click on the node of treeview the nodes are added again. how to disable the click event of treeview.
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?

I'm trying to enable/disable buttons in my gridview according to a value in gridview's field.
But everytime when I try to run my page, it shows me below underlined error and point to my gvTimeSheet.DataBind() in page_load.
"Unable to cast object of type 'System.EventArgs' to type 'System.Web.UI.WebControls.GridViewRowEventArgs'."
I also tried to enable / disable button in HTML but it just against from what I need it to be.
Example, sheet_status = true, I do not need to enable the button.

View 4 Replies<asp:LinkButton ID="LinkButtonNewServicesCategory" runat="server"
OnClientClick="this.disabled=true;return false;"
style="float:left;margin-right:5px;" CausesValidation="False">new services category</asp:LinkButton>
The intent is that when the LinkButton is clicked, it disables itself and returns false to prevent the postback (this control is used as a trigger for an animation).
In asp.net(C#) i'm using masterpage and childpage.
in masterpage i used TreeView Navigation control to view the Childpage.
.What my doubt is......when i select the navgation control
my TreeView Control should be disable and when i click cancel button in Child page it will enable..

I have searched around but unable to find a solution that will work. I have a link button that is created dynamically during the page load. It is given an ID (obviously). There is a script manager on the page. I have the controls added to a panel in the updatepanel (updatePanel1). There is a dynamic label that is also created with each link button. I can get a response from the linkbutton click event during a postback on the second time clicking the linkbutton, but I am getting a complete postback instead of the asyncpostback for that control. During the creation of the dynamic linkbuttons, I am also creating a dynamic trigger for each button and adding it to the updatePanel1. The Click event is not firing the method without doing a complete page postback.
View 4 RepliesHave a gridview that is populated via a DB, which is populated by another tool. That tool records all the data, including the user that submitted it.
The site also enables editing, but I want only the user that submitted the data to have the ability to edit HIS data only, even though the grid view is displaying other people's datas.
So currently the gridview has "ShowEditButton="True"
So on the far left, there is the Edit option for all lines, for all users, for any user viewing the site.

View 5 RepliesI dont know what happened but none of my buttons or linkbuttons causes a postback anymore. I have dragged a few updatepannels on the page but the linkbutton concerned is not enclosed within an update pannel. when I click it there is just no postback happening anymore. I set the debugger at Page_load but...its not reached. I used firebug to analyse the http requests. there is none. its like those are not considered buttons anymore.
View 5 RepliesI 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
