Ajax based web application breaks on html tag in text field meenakumar27-Mar-09 6:01 meenakumar 27-Mar-09 6:01  Hi, In my application, I enter a string as "Show Names" in a text field which is in updatepanel. This string is stored in database. later on another page this string is used to populate the column header. The column header displays properly as Show Names with break after the string "Show". now I go back to previous page where it loads the values saved in database. There is a check box in the same update panel , clicking on it causes a postback. But then it causes a server error with code 500. It is caused by string in the text field. At any cost I need this line break for the column header from the saved column header string. How to resolve this issue? Thanks kMeena Re: Ajax based web application breaks on html tag in text field Yusuf27-Mar-09 6:11 Yusuf 27-Mar-09 6:11  meenakumar wrote: error with code 500. This is not helpful. You need to debug your code and see where it is breaking. Also uncheck "Show Friendly error" in the tools->Internet Options-> advanced menu, if you are running IE. that may be give you a better error.

A little bit ambiguous Re: Accessing dropdownlist in footer of gridview from javascript nainakarri27-Mar-09 7:57 nainakarri 27-Mar-09 7:57  Thanks for the reply. I have a gridview as below <asp:gridview id="grdv" runat="server" showfooter="true" xmlns:asp="#unknown"> <columns> <templatefield> <edititemtemplate> dropdownlist dropdownlist now i want to access the dropdownlist and its values present in edititemtemplate and footer of gridview from javascript. Also i want to add/remove the values from dropdownlist. Thanks Naina Re: Accessing dropdownlist in footer of gridview from javascript Ibrahim Bello30-Mar-09 6:02 Ibrahim Bello 30-Mar-09 6:02  Are you constrained to using Javascript? Otherwise, it's easy to access the template control from codebehind using the FindControl function. What are you trying to achieve? Again I think we need more code than you've provided for us to adequately help you. 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!

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[^].

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..
