Disable only the link part of a ASP.Net LinkButton

I have a ASP.Net LinkButton in a Repeater. In some conditions on some rows i'm trying to disable the link of the button so that it acts more like a Label, where other rows will be a link that fires off the ItemCommand event.
What is a good solution for this? I'm trying to avoid having two separate control on the page to handle pretty much the same thing.
Anyone have experience with this?

Wire into the ItemDataBound event for the repeater. In each item, find the link button, and then use a method like on this solution to disable the link button on an item by item basis
How to completely disable the link button?

Wiring up a dynamically created LinkButton that is being inserted into a PlaceHolder that is in a ListView Item

I have a ListView that is outputting line items that each have a PlaceHolder object.
Within that PlaceHolder I am outputting any number of LinkButtons.
I am adding a Click event Handler to each Link Button to invoke a code-behind method.
HOWEVER,
The method is not being fired when the link buttons are clicked. I need help determining why this is and how I might be able to fire a method in the code-behind when one of these Link Buttons are clicked.
I have already performed the process of storing the LinkButton controls so that they repopulate the Placeholders after a post back. (They don't disappear when clicked).
All suggestions welcomed! Thanks!

Simplest way to create a cell on-click event(or like one) for asp gridview

I have looked at numerous articles on how to make on-click events and the best I could find is rowclick, even then it was not very clear on what you have to do. Some use rowcreated event some combine rowchanged and selectedindexchanged, others have said columnindex and rowindex. All I want is for users to be able to click the cell and it show the value in a textbox on the page. Please someone tell me the most simplistic way of doing so. (WITHOUT USING A BUTTON) Thank you for your help.

For just displaying the value of a clicked cell in a textbox I suggest using javascript.
Using a library like jQuery there is not much code to write:
$('#clientIdOfGridViewTable').on('click', 'tr > td', function(event) { $('#clientIdOfTextBox').val($(this).text () });
I am writing this on my phone so the code above might need tweaking.

C# ASP .Net, triggering button control inside Gridview

I have a question about button inside the gridview. As the title says, I designed a gridview with a button inside. Whenever I trigger the button, it always binding the gridview before it can reach the button event.
Say, onLoad page, I pull data and bind them to a gridview, then I would like to do a mass update which will be triggered by the button inside it. If i put !IsPostBack, it never triggers the button event, which means it always has to read the data bind them into gridview again then execute the button event.
Problem is, I have a huge data and it takes much time to update because of it. I am wondering if there are any ways to trigger the button event without rebinding the gridview again? Is it because of the button inside the gridview so it is necessary to rebind again before it could read the button event?
Any suggestion would be really appreciated.

Why don't you use the RowCommand instead of the onclick event?
you can add a command name property to the button to understand what operation you need to do
Have a look at the link below and just replace the ButtonField with a classic button. don't forget to assign a CommandName

You should not use the button event, but the GridView.RowCommand event instead. See here. If you do this in combination with the if (!IsPostBack) check in Page_Load, it should work for your scenario.

your button must be triggered by OnRowCommand event and ! IsPostBack shouldn't prevent triggering your button
protected void GridView_RowCommand(object source, GridViewCommandEventArgs e)
{
if(e.CommandName=="Update")
{
// put your update code here
}
}
and you can use ajax to update your datasource without rebinding your GridView and update your UI using javascript.

FindControl in DetailsView Not working?

I have a Gridview and when the edit button is clicked the details of that row is displayed using a detailsview.
While displaying, I need to find a control in detailsView, and then bind it with a Datasource.
First of All I'm not sure about the event to be used but have used DetailsView1_DataBound. However, if I have to find the control using
var control=(ControlType)DetailsView1.Findcontrol("ID");
Always returns null. May be I am not using the right event, and it couldn't find the control at that point. Any ideas about the event to be used, and the right code please?
Thanks

In your databound event, you need to take care your DetailsView Mode
if (DetailsView1.CurrentMode == DetailsViewMode.Edit)
{
//Put here if you want to find control of your Edit Mode
var control=(ControlType)DetailsView1.Findcontrol("EditTemplateControlID");
}
if (DetailsView1.CurrentMode == DetailsViewMode.Insert)
{
//Put here if you want to find control of your Insert Mode
var control=(ControlType)DetailsView1.Findcontrol("InsertTemplateControlID");
}

I had the same problem and the answer of Muhammad Akhtar did not help me. The problem was solved after changing the default mode of the DetailsView from 'edit' to 'insert'.
I would also recommend the ItemCreated event instead of the DataBound event. I use it often for setting a default value in a field of the DetailsView.
