Try to use PreRender in DataGrid:
Private Sub grd_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdDefinitionList.PreRender
grd.Columns(1).ItemStyle.Width = Unit.Pixel(24)
grd.Columns(2).ItemStyle.Width = Unit.Pixel(24)
grd.Columns(3).ItemStyle.Width = Unit.Pixel(24)
End Sub

So can u explain me more and sort out this Problem...

hi
you can set the width of any column in datagrid in html itself as below:
<asp:BoundColumn DataField="Id" HeaderText="Id" ItemStyle-Width=20%></asp:BoundColumn>

U can convert the columns to template column in property builder
then set following properties according to your requirement:
<asp:TemplateColumn ItemStyle-Width=25% ItemStyle-VerticalAlign=bottom>
<ItemTemplate >
<asp:Label id="Label2" runat="server" ></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox id="TextBox2" runat="server"></asp:TextBox>
</EditItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn>
<ItemTemplate>
<asp:Label runat="server"></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server"></asp:TextBox>
</EditItemTemplate>
</asp:TemplateColumn>

Hi,
My web application is hosted on windows2003 server (IIS 6.0).I am facing
one strange problem on client machine, i use response.redirect("url for
Office document like .doc,.xls") to open the any attacment with the records,
in some of the machine the attachement open properly but in some it's not(it
seems like client gets back the response and page appear for fraction on time
and gets dissapear.) even when i run the application on server itslef i
notice that attachment getting open when i use http://localhost in my url but
problem occurs when i use IP address or machine name. Is it something related
to IE setting or some setting of IIS.
but the things work perfectly on any machine if attachment is pdf file.
Any help will be appreciated.

Ritesh

Do following steps.
1. Include "Microsoft Office 11.0 Object Library" on your project and get file content of your file using following steps
Word.ApplicationClass wordApp = null;
Word.Document doc doc = wordApp.Documents.Open(ref file,ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing,ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,ref missing, ref missing, ref missing);
//Save the contents of File in database as
string str = doc.Content.Text;
//Save str to database
2. Open a temp page as follows.
Response.Write("");
Response.Write("window.open('temp.aspx');");
Response.Write("</"+"script>");
3. On this temp.aspx page load do following steps
//Retrieve File contents eighter form database wich we have saved in step1
byte [] FileContent = (byte[])row["FileContent"];
Response.Clear();
Response.AddHeader("Content-disposition", "inline;filename="+FileName);
Response.ContentType = "application/msword";
Response.BinaryWrite(FileContent);
Response.End();
//If this not works then do following
HttpContext.Current.Response.BinaryWrite(FileContent);
Response.End();

Hi Abhishek,
thanks you very much for you reply.currently i am doing same steps,i.e opening temp. page and doing response.redirect to target file,It was my mistake that i forgot to mention that my application is sort of document management system and it stores file with any extension on FTP server.As sugested by you in Step 3 is mainly deal with msword documents,but i am also facing same problem with autocad (.dwg) files. and in my temp page i am also doing further proecessing of file like converting it into pdf format and applying watermark onfly etc, so i guess converting files into binary format further slowdown the whole process (as size of files are in 10+MB). I am not sure but i guess it has something to do with mime setting as when i added *.* in the mime type list of my iis server it's work file (but only if i use localhost in my url).
If you can have any suggestion i would be very helpfull....
thanks,
Ritesh

Hi All,
Wonder if you can help me with this one?
I have a datalist with an EditItemTemplate defined. Within the EditItemTemplate I would like to have a radiobuttonlist that allows the user to specify the type of item. The radiobutton would autopostback and, depending on which radiobutton was clicked, different textboxes would become visible within the line item that is currently being edited.
I can't figure out where to put the code to capture the radio button that was selected and thus make the relevant text boxes visible in the edititemtemplate.
Any help would be greatly appreciated.

What you need to do is to create a handler for the SelectedIndexChanged of the RadioButtonList control and you can use the SelectedXXX properties of the control to access the selected item.

Hi minhpc_bk, Thanks for the reply.
The event handler gets called as you would expect when the radio button list is on the form in a "usual" position, but if I put it in the edititemtemplate the handler is not called. I added OnSelectedIndexChanged to the control and now the handler is called but the RadioButtonList1 object is Nothing.
I ended up having to get set up a datalistitem object using
datalist.item(datalist.EditItemIndex)
then using datalistitem.findcontrol to grab the radiobuttonlist.
But hey, it works now and you pointed me in the right direction, so thanks!

There is no reason why the newline should not be saved. I think that it's saved all right, but not displayed the way that you expect in the user interface for the database. What database are you using, and what user interface do you use to view the data?
