Nov 24, 2010
i have a grideview which their is a LinkButton control i want to wite some code in that event i i do that. I am providing the code for better understanding
in my webpage gridview is there in that gridview gridTags_Updating event is there.when am keep a breakpoint inin that event will not fire as well as when am clicking update button gridview is disappear
I have a datalist that loops thru cart items. Within the datalist template I call a user control that has a small form that gets repeated for each item. When this control is called outside of the datalist, the form submits fine, but when called within the datalist the button has no event action. I've tried adding an event handler to ItemDataBound of the datalist, but still no event action. How can I get my form to submit?
I've got a GridView control with LinkButtons in different cells. Currently when someone clicks a link, it fires the ItemCommand passing the CommandName and the ID of the item the link is bound to. That all works fine. I need to modify it now to not use links anymore. It now needs to show a popup balloon with a link (styled to look like a button) and when the link is clicked, I want it to do the exact same thing. I'm sure there are several ways of doing this, but for time's and consistency's sake, I'm copying the method used from another page we have that is already doing this. It has a hidden DIV on the page with the link in it. When you hover over a link, javascript repositions the div and makes it visible.
So what I need to do is pass my CommandName and item ID to the javascript so that it can trigger the postback when they click that single link. I know this is not the only way to get to the end result, but what I want to do if possible, is still fire the GridView's ItemCommand and set he DataListCommandEventArgs' CommandName and CommandArgument properties. Can someone explain how, under normal circumstances, clicking the LinkButton in the GridView fires the ItemCommand? I know that the LinkButton's click event is forwarded to the GridView but what gets sent from the client side that let's the server know the link was clicked?
I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages: [CODE] CmsContactUsContent += string.Format(" "" + "" + "
i have two nested gridview inside an update panel. there is a button called btnPhoneEdit inside the child grid view. when the button gets clicked, it do cause partial post back as expected but it fails to invoke btnPhoneEdit_Click.

I am using a dropdownlist in my application and it has corresponding SelectedIndexChanged() event.I would like to invoke GridViewEdit Event when SelectedIndexChanged event fires from dropdown list.Is it possible to implement this...??
<asp:DropDownList ID="ddlStatus" Visible="true" AutoPostBack="true" OnSelectedIndexChanged="ddlStatus_SelectedIndexChanged" runat="server"> </asp:DropDownList> protected void ddlStatus_SelectedIndexChanged(object sender, EventArgs e) { //Code to fire the GridViewEdit Event to put a row in edit mode }
I have one Datagrid with Footer. Footer Row Contains Input fields with one Button to add New Values. I have button click event but not getting fires. my code follows:
I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a <div> tag with visible=false.
I'm customizing a NopCommerce store, and am using a gridview to display and sort the products. All that works well. I like how the external pager (user control) works with the gridview, with one exception -- it uses the hyperlink control, so I lost viewstate, which I need to retain for both the search page and to retain the gridview sort options. Based on the page selected (from the pager control), I query the database and rebind the gridview. So, I switched the user control to use LinkButtons instead of Hyperlinks. This is the sample code for one of the buttons:

I set a breakpoint inside the lbCommandClick method, but it never gets hit. Reading other posts tells me that I would have to add the dynamic controls in the OnLoad method, but since this all happens based on other data on the page (say search results), I don't think I can do it onLoad. However, the link buttons do work to cause a postback, and my viewstate is saved correctly. The only problem is that I do not know which button was clicked. I could check Request.Params["__EVENTTARGET"] onLoad, but that is kind of a hack -- I'd much rather be able to set the event handler in the user control and use the CommandArgument property. But, what I have tried so far fails.
Especially one that would allow me to set the EventHandler in the User Control? (e.g. OnlbCommand="PagerLBPageChange" )
lets say I have a control with a button in it. I want to use my control on a page but then know when the button in the control has been clicked. I assume I need to fire some sort of event when the user clicks the button and then in my parent page I can hook into onMyCustomEvent or something..
In my web app, I used LinqDataSource, ListView and DataPager (.NET 3.5 sp1) to implement search feature with paging. I have a button to trigger the search.
But In the first time, the Selecting event of LinqDataSource fire twice and I don't know why (I debugged my code very carefully). I don't use QueryString with DataPager and assign PageSize of DataPager in the first time of page load to prevent the ListView bind again (as in some instructions I found in forum)
Kindly, see the following image. This is my Gridview with separate paging on the top right of the image. The arrows are Image buttons and the right text box is read only.[URL]
I run my page for the first time everything runs perfect. I move to other pages of the grid still perfect. Then i move to other aspx page and then come back. The page loads perfect with the old page number there still perfect. Now if i press any image button then the text change event fires which should not fire.
Note: i need the text change event as i user randomly enters something in the text box then i have to handle that.
Example:
When i return from the other aspx page then the value in the Page Number text box is lets say 4. Then i press the Back image button and a post back happens. The Value in Text box is still the same 4. Then y the event is firing ???
I am not understanding that why this event is firing. On the page load, i retrieve the values from hash table (The hash table is stored in session in base page) and from the hash table i get the pageNo and assign it to the page No text box.
Here, is my one of the image button event. (Remaining image button events are almost same)
[Code]....
My text box change event.

My page load Code: Note: PageUniqueIdr = PageUniqueId retrieved from the QueryString.
THE LAST METHOD _insertin is NEVER FIred UP. The Update pases correctly ands I will not give the code for the object data source.
My purpose is to include code into on insert code that assign value to a column .
