Changing GridView Column Header Ibrahim Bello27-Mar-09 5:13 Ibrahim Bello 27-Mar-09 5:13  Hi, I've designed a templated ASP.NET GridView Control. What I want to achieve is to change the HeaderText of one of the columns based on a DropDownList SelectedIndexChanged event. I placed a label into the HeaderTemplate: <headertemplate> <asp:label id="lblValueRate" runat="server" width="64px" xmlns:asp="#unknown">"" If a User selects 'Value' from the dropdownlist then I set the Text property of lblValueRate to 'Value' and if User selects 'Rate', changes to 'Rate'. <asp:dropdownlist id="dbcValueRate" runat="server" autopostback="True" xmlns:asp="#unknown"> <asp:listitem>Rate <asp:listitem>Value I've tried implementing it this way without success: Label lblNew = (Label)GridView1.HeaderRow.FindControl("lblValueRate"); Then set lblNew.Text = Rate or Value This didn't change the GridView Column Header so I thought perhaps I wasn't getting a reference to lblValueRate. So I tried using pointer in unsafe code, Like this: Label* ptrLabel = &((Label)GridView1.HeaderRow.FindControl("lblValueRate")); and dereferenced it this way: Label lblNew = *(ptrLabel); But throws up error that can't get address of managed control. I believe this is very trivial, but I seem stuck here. Thanks! Re: Changing GridView Column Header Ibrahim Bello27-Mar-09 8:23 Ibrahim Bello 27-Mar-09 8:23  Yeah, I've solved the issue. The code works as it is. Made a few mix-ups elsewhere in code. It's interesting that the assignment, Label lblNew = (Label)GridView1.HeaderRow.FindControl("lblValueRate"); copies the address as well, rather than just the value as we have, when we copy one variable to another? It was this consideration that made me consider using pointers as an alternative - thankfully, .NET does the 'dirty work' for you. Or so it seems. Thanks everyone!

I have a requirement where i want to open modal pop up on selection of either yes/no from radio buttons. Targetcontrolid of modal pop up extender is id of selected radiobutton.

Yusuf27-Mar-09 3:53 Yusuf 27-Mar-09 3:53  fckeditor is just an editor. You can use whatever editor your feel comfortable with. I guess what you are looking for is User Controls[^]. Yusuf Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^] Caret disappears when tabbing Lonnie Raffray27-Mar-09 2:49 Lonnie Raffray 27-Mar-09 2:49  I have several TextBox controls with initial values. When I tab between them, the OnFocus event blanks out the initial value by setting value="". When this happens, the caret disappears. This gives the user the impression that the control has lost focus, but it hasn't. This does not happen if you click in any of the TextBoxes with the mouse, only when tabbing into a TextBox. Any ideas? resize calendar control meghamaharshi27-Mar-09 2:38 meghamaharshi 27-Mar-09 2:38  Hello Everybody I am using asp calendar control on my web page but its big according to the page i have set its width and height but its not resizing..

Re: resize calendar control Ravi Mori27-Mar-09 2:47 Ravi Mori 27-Mar-09 2:47  I guess this thing happens because the size of div or table is large where you put this calendar control.. so first of all checkout size of that where your control is... if i am not right then give some description or code.. thanks..

If it can be accessed from within your website code, I guess you'd have to try and see. Christian Graus Driven to the arms of OSX by Vista. Re: can we make changes in web.config using C#?
