Are there any restrictions on using templatefields in gridview if the gridview is inside an updatepanel?If I click on the imagebutton, I get a exception which I can't seem to figure out.
Sys.WebForms.PageRequestManagerServerErrorException:
Invalid postback or callback argument.
Event validation is enabled using <pages enableEventValidation="true"/>

In a gridview I have a TemplateField containing an imageButton defined as:
<asp:TemplateField>
<HeaderTemplate>
HeaderName
</HeaderTemplate>
<HeaderStyle HorizontalAlign="Center" />
<ItemTemplate>
<asp:ImageButton ID="imgName" ImageUrl="./img/img.png" runat="server" style="cursor: crosshair;" OnClick="imgName_Click" />
</ItemTemplate>.......
Now the odd thing at run-time is, whenever a client-side mouseover event is triggered, the app does a full postback. That happens only in firefox.

View 1 RepliesI am having a custom ASPX page with following structure. Its having 2 update panel and I have a ImageButton outside them. The two UpdatPanel are triggered by this ImageButton.The Problem is whenever user clicks the Imagebutton, the image in the ImageButton is getting reloaded...it disappears and the reappears. I am not able to figure out why the postback is happening when the imagebutton is place outside UpdatePanel. Is it because I am using this Imagebutton for triggering AsyncPostBack in UpdatePanel?

have a created a dynamic solarsystem map. Basically I have a updatepanel which inside I programattically create imagebuttons of the 'planets'. These imagebuttons are given a Command event and when clicked the idea is to set the clicked planet in question as the parent and redisplay the map.Inside the command event I pass in the ID of the planet and this sets a session varible. The panel load event is then designed to use this session varible to set the new parent and display the child 'moons'

<asp:Label ID="Label1" runat="server" Text='<%# Eval("Date").ToString() =="2000/01/01 12:00:00 AM "? "" : Eval("Date" ,"{0:dd/MM/yyyy}").ToString() %>'></asp:Label>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
The Problem i having is that i am testing weather the date matches something and based on that it display "" else it should display the date based on the formotting but both are not working.
In my gridview, I have 6 columns. The first 5 columns are filled with data retrieved from database.In the 6th column I want to display a value from textbox from same form. The value should be displayed on the row next to last row of rest of the columns. So my last column (i.e.) 6th column will just have all the rows filled with the same value of the text box.
First 5 columns of grid will be filled by selecting the college name from dropdown.The last colum (Date) must be filled with the date that is given in the textbox.It can be even after button click event(date of attendence).
It can be done after button click event also..

I have a table with lots of fields. To display every record that has lots of columns on a web browser will inconveniently force the users to drag the scrollbar to the right.
Is it possible to divide each record to two or three inner rows in gridview?
e.g. My table has these fields: - UPC - Description - AdType_Week1 - AdType_Week2 - AdType_Week3 - AdType_Week4 - AdType_Week5 - Price_Week1 - Price_Week2 - Price_Week3 - Price_Week4 - Price_Week5 - OrderStatus_Week1 - OrderStatus_Week2 - OrderStatus_Week3 - OrderStatus_Week4 - OrderStatus_Week5
Instead of showing everything in one header like this:
UPC | Description | AdType_Week1 | AdType_Week2 | AdType_Week3 | AdType_Week4 | AdType_Week5 | Price_Week1 | Price_Week2 | Price_Week3 | Price_Week4 | Price_Week5 | OrderStatus_Week1 | OrderStatus_Week2 | OrderStatus_Week3 | OrderStatus_Week4 | OrderStatus_Week5
I would like to show it like this:
|-UPC-|-Description-|-AdType_Week1------|-AdType_Week2------|-AdType_Week3------|
01 banana type abc type def type feg
|-Price_Week1-------|-Price_Week2-------|-Price_Week3-------|
$97.51 $78.48 $41.45

I'm trying to change the visibility of a imagebutton to false, if the imagebutton.ImageUrl="". The problem is that the imagebutton is inside "ListView2", and "ListView2" is inside "ListView1". Who can I do this in vb code... or even a javascript.
