Web Forms :: Load A User Control On Link Click Event Of A Link Button During Postback Of Aspx Page?
Mar 2, 2011Here is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
Link Button And JavaScript / Change A Standard HTML Input Button To A Link Button
Mar 1, 2011I need to change a standard HTML Input button to a Link button but am running into problems because the existing
code calls a javascript function. The function basically does the same as the browser back button. When I add the code and
set the property runat="server" I get a "CS1026: ) expected".
Quite new to ASP,net (VS2010) so could be going about this the wrong way.

View 3 RepliesLink Button On User Control Not Firing?
Feb 6, 2010I have a user control, which is added to another user control. The nested user control is built up of a GridView, an image button and a link button. The nested user control is added to the outer control as a collection object based upon the results bound to the GridView.
The problem that I have is that my link button doesn't work. I click on it and the event doesn't fire. Even adding a break point was not reached. As the nested user control is added a number of times, I have set image button to have unique ids and also the link button. Whilst image button works correctly with its JavaScript. The link button needs to fire an event in the code behind, but despite all my efforts, I can't make it work. I am adding the link button to the control dynamically. Below is the relevant code that I am using:

View 7 RepliesWeb Forms :: Link Button On User Control Not Firing?
Feb 5, 2010I have a link button which is part of my user control. Further, the control is actually added to the control dynamically. Whilst, I can see the control, and is added to the page without any visible errors, but when I click on to fire an event which on that user control nothing happens. What is even more odd, if I add a break point to event, and then click in debug mode, I can't even reach the break point!
To try and resolve this, I have tried giving the link button ids, and ensured they unique, added override using OnInit and used the createchildcontrols method, but nothing seems to work!

View 2 RepliesWeb Forms :: Getting Linkbutton Text Value From Link Button In User Control?
Nov 9, 2010i have a link button thats text value is populated from a dataset value retrieved from a database. When the user clicks on this link button I want to somehow capture the text value. The trick is the linkbutton is within a usercontrol, and I want to do the processing from the user controls parent. I am able to get the ID of the clicked linkbutton with the use of Request.Form["__EVENTTARGET"];, however i need the text value, in this case its a job number.
I may be able to do this via javascript with the OnClientClick;
OnClientClick='<%# DataBinder.Eval(Container.DataItem,"JobNo","test({0})")%>'
When I do this I get a javascript error saying "M10725"(which is my job number being clicked) is ndefined. I dont know what this means. Do I somehow have to give the linkbutton being click a value?

Javascript - Unable To Bind Event With Link Button On User Control
Nov 3, 2010There are two user controls, which are built dynamically.
In the first control, I am adding a link button, and trying to attach a click event on the same. But the event is not fired.
Actually the main goal is, when the link is clicked, based on which one is clicked, I need to show second control (the values on the new controls are based on the first controls link button that is clicked).
If I use javascript, I will need to use ActiveX or is there any other way to instantiate the second control using javascript

Forms Data Controls :: Gridview Link Button Control Click Event?
Sep 28, 2010I have Web page that uses LinkButton control inside Template Fields of Gridview.I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.
I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.I also tried to use OnClick Method, Session variable and Hidden variable. but when i run Response.Redirect method from Gridview_RowCommand, it clear all the Session and Hidden variable values. also tried (Response.Redirect(,false)) method but never got success.
