Is it possible to use a TemplateField (or any *Field from a GridView) inside a user control (ascx).
I have a complex TemplateField (item, edit, footer) that I would like to easily reuse.
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"/>

I have a FormView inside a user control, and in the InsertItemTemplate, I have an AsyncFileUpload control, that I would like to to use. On the user side, it seems to work, but it doesn't work on the server side code behind. The HasFile Property is always false, and it doesn't fire the UploadCompleted event either. My UpdatePanel is in the master page.
<asp:FormView
ID="frmAddImage"
runat="server"
DataKeyNames="imageID"
DataSourceID="sqlImages"
Width="100%">
<InsertItemTemplate>
<cc1:AsyncFileUpload
runat="server"
ID="FileUploadImage"
Width="400px"
UploaderStyle="Traditional"
CompleteBackColor="Lime"
ErrorBackColor="Red"
onuploadedcomplete="AsyncFileUpload_UploadedComplete"
UploadingBackColor="#CCFFFF"

Referring to the following: Ajax Asyncfileupload doesn't work as soon as I put it in a control I am having the same issue. I am not using a Master page though. I have an AsyncFileUpload control in a Panel, within an update panel.

I have a SQL2012 database in the database in have a table with many cloumns one of the columns is date. on the gridview i am using a ItemTemplate field to display date
<asp:TemplateField HeaderText="DATE">
<ItemTemplate>
<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 textbox  where user entres his mail and clicks the button. I have also the grid  where I have the hiddenfiled.Â
On button click I want to pass the value from the textbox to the hidden field. How do i do that?Â
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 need to create a TemplateField column dynamically , which will contain dropdowlist controls. I've been using this
example to create my first dynamic columns and for the last column, the one that contains dropdowlist controls, I've written this class:
[Code]....
But what I don't know is, where should I populate the dropdownlist control?
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.

AsyncFileUpload not working with IE9. only on capability mode
View 9 RepliesI have an updatepanel to which I am adding a web user control dynamically. This web user control has an AsyncFileUpload. I have read several articles that tell that asyncfileupload control will not work if added at run-time. As suggested by some of the articles,I tried adding a static asyncfileupload control but still it does not work.I need to have 5 file upload controls in the web user control. Do you think I can make them to work or should I completely do a re-design or go with full postbacks. My preference is to be able to use asyncfileupload control and I am willing to invest time in making them to work since they improve the user experience by many folds.
View 3 RepliesI am using an AsyncFileUpload control in my asp.net page.This control in inside an update panel.Any post back(like some treeview loading,combo selection in which i needs postback) appear in that page makes the AsyncFileUpload control text area gets cleared.Is there any solution to retain the selected file name in the AsyncFileUpload control after the postback.
