Hi,

I was trying to sort a GridView programitically but my code is throwing an System.StackOverflowException.Please have a look at the code below and reply what wrong I m doing.

protected void GridView2_Sorting(object sender, GridViewSortEventArgs e)
{
GridView2.Sort("CarrierCode", SortDirection.Descending);
}

CarrierCode is the name of a column above.

Thanks.

You are getting a stack overflow operation because this event occurs when the hyperlink to sort a column is clicked, but before the GridView control handles the sort operation.
GridView.Sorting Event
[^]
What is happening is your GridView2_Sorting function is executing which calls the sort method. This in turn will cause your GridView2_Sorting function to handle the sorting event thus getting stuck in a loop until the stack overflow exception is raised.
See C# GridView Sorting at http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/gridview.aspx[^]
for help with sorting.

How to access server-side controls of a user control(ascx) from its parent page (aspx) by using javascript

Hi all,

I have already found the approaches to access server-side controls of a user control (e.g <asp:label> <asp:textbox> ...) on IE,

var obj = document.getElementById('uctAUserConrolID_AServerSideControlID'); //or
var obj = document.getElementById('uctAUserConrolID:AServerSideControlID'); //or

BUT, these approaches don't work on Firefox!!! Frown | :(

please let me know if anyone know the answer.

Thanks

Correct me if i'm wrong, but firefox doesn't use getElementbyId, does it?

Hi,

The firefox do use getElementbyId, because I tried this piece of code below to get the client-side controls within a user control , it works.

var obj = document.getElementById('AClientSideControl');

You can view the HTML ViewSource in both IE and Firefox. And find out what the name of your element. then, I think you will get some idea how to get the object of your element in Javascript. If not, can you please the name of your name which is shown in the viewsource of IE and Firefox.

Hi Michael,

Thanks for your help, I did use the way you suggested. The HTML ViewSource for the asp:net control in both IE and Firefox are actually same: D'Oh! | :doh:

For Firefox:
<input name="UctLogin1:txtEmail" type="text" id="UctLogin1_txtEmail" />

For IE:
<input name="UctLogin1:txtEmail" type="text" id="UctLogin1_txtEmail" style="width:200px;" />

var obj = document.getElementById("UctLogin1_txtEmail"); doesn't work? You got the error or got nothing? Have you tried to debug your javascript by using Firebug?

No, it doesn't work with getElementById, no error shown in Firefox error console.

the result show null. but anyway, getElementsByName works .. Laugh | :laugh:

Hi Michael,

Problems solved, I use getElementsByName with its name in HTML ViewSource instead of ID, it works! Wink | ;)

It seems like the getElimentById function still does not work compatiblely with firefox very well.

hello everybody

on my grid view i have a select command button. on gridview select click i want to pass memberID and propductID of that row and fill up modal popup with member details and product details.

thanks in advance

Use the button's CommandArgument and CommandName property to store the memberID and propductID as in:

<br />
					                                <asp:Button id="btnPopUp" CssClass="btnStyle0" Text="View product" CommandArgument='<%#DataBinder.Eval(Container.DataItem, "memberID").ToString()%>' CommandName='&lt;%#DataBinder.Eval(Container.DataItem, "propductID").ToString()%&gt;' runat="server"><br />
						                            </asp:Button>

Add a click evnet to the butten as in:

<br />
void btnPopUp_Click(object sender, EventArgs e)<br />
        {<br />
Button btn = (Button)sender;<br />
memberID = int.Parse(btn.CommandArgument);<br />
propductID = int.Parse(btn.CommandArgument);<br />

Then use this values to get the data you need and push out an PopUp.

Remember to add the buttons clik event in the GridView's OnItemCreated.
Hope it helps

Hello Friends,

When we use Servert.Transfer and set it's second parameter true then sometime it throws error

Can anybody let me know y it's happened ????????????????/

You haven't stated what error your are experiencing. However, the MSDN documentation states

Transfer calls End, which throws a ThreadAbortException exception upon completion.

This would not be affected by the value of the preserveForm parameter, which simply determines whether the QueryString and Form collections are preserved.

<blockquote class="FQ"><div class="FQA">The Knowledge wrote:</div>Can anybody let me know y it's happened ????????????????/ </blockquote>

Is the '?' key stuck on your keyboard?

Is this label in template column? If yes, you can find this label in RowCreated event or RowDataBound and then set the backcolor.

For example ~

<br />
RowCreated or RowDataBound<br />
<br />
Label lbl = (Label)e.Row.FindControl("lblColore");<br />
lbl.BackColor = //Set your color here.<br />
<br />

Hi,

you can set multiple QueryString

<br />
string tempURL = "~/MySite.com/Welcome.aspx?Name=" +MyName+ "&Surname="+MySurname;<br />

Now on Welcome.aspx page you can get this both values like this.

<br />
if(Request.QueryString.Count>0)<br />
				{<br />
					if(Request.QueryString["Name"].ToString()!=null)<br />
					{<br />
						Name= Request.QueryString["Name"];<br />
					}<br />
					if(Request.QueryString["MySurname"].ToString()!=null)<br />
					{<br />
						MySurname = Request.QueryString["MySurname"];<br />
					}<br />
				}<br />
