I am not sure of the right method.

But U can try this.

Using System.Collections;

if (grid.Rows.Count==0)
{
ArrayList arr=new ArrayList ();
arr.add("");
arr.add("");
arr.add("");
//and so on(now 3 empty rows will be displayed).

grid.DataSource=arr;
grdi.DataBind();
}

Hope this helps U.

Try Using this..
if (ds.Tables[0].Rows.Count == 0)
{
ds.Tables[0].Rows.Add("", ""); //Add empty string that corresponds to the number of columns
grdOrders.DataSource = ds.Tables[0];
grdOrders.DataBind();
grdOrders.Rows[0].Visible = false;
}

The gridview has an emptydatarowtext that you can use to display some text or you can use the emptydatarowtemplate to display some html.

Hope that helps.

That is what you can use the emptygridviewtemplate for. I suggest running you app when you have data in the gridview. Go to the browser view - source, copy the html code. Paste it into a emptygridviewtemplate. Remove the data, just leave the header. You should be all set.

I guess I gave you the wrong name. It is emptydataTemplate. It goes in the gridview. Here is a link:
<a href="http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.emptydatatemplate.aspx">http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.emptydatatemplate.aspx</a>[<a href="http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.emptydatatemplate.aspx" target="_blank" title="New Window">^</a>]

The basics are:
right before the </asp:GridView> tag you need
<EmptyDataTemplate>
put your html here
</EmptyDataTemplate>
</asp:GridView>

Hope that helps.

He is asking what to write in the place where U have written

"put your html here".

Please run the application in such a way that the grid shows data.

Open the Page source from IE or FF.

Locate the tag
<Table>

and copy the first row with tr and th tags.

Paste them in that place.

Dataset's

 Dim Data As DropDownComboData = New DropDownComboData<br />
<br />
            ' use following codes to retrieve data when data request is invoked from client.<br />
            Dim TopRows As Int32 = e.StartRow + e.RowCount<br />
<br />
            Dim ds As DataSet = Data.Bank_Lookup(e.QueryText, TopRows)<br />
<br />
            e.DataSource = ds

I have the following code which creates a DataSet using the arguments passed to it from a control's event. The code works fine but as a requirement of the control it also requires a Count passed to it. Originally I created a new stored procedure to get this but it would make more sense to pass this back with the resultset. This would mean one stored procedure to do it all. I have created the SP and it returns a resultset and now a second resultset which just includes the scalar count value.

What is the syntax to get this single value? Something like

<br />
Count =  ds.Tables(1).Rows(0)

Is that correct??

i think this code might help you

<br />
object[] itemsInOneRow=ds.Tables[0].Rows[0].ItemArray;<br />

now again iterate through the itemsInOneRow it will give what you want Smile | :)

Page timing out?

hi,

I am running a complicated page which is looping through all of the folders beneath a specified folder, then looping through all of the files within each folder. Then for each file, I am doing a check on the name (Format, length etc.) then if it is correct moving it to a different drive on a different server, creating the relevant folders to house the files, and again with the incorrect files. This all works fine but after exactly 1 hour, the page seems to time out and displays the "This page could not be found" error page.

I am assuming it is a timeout as it is always after an hour.

I have changed the httpRequest executionTimeout to be over 3 hours (as that's what i expect it to be at least, due to the No. of gigs being shifted by the app!).
The session state timeout is 480 Mins so that isn't the problem and everythings being done with server-side script (c#) so it shouldn't be client-side script timeout.

does anyone have any suggestions?

thank you

how to unchecked the radio button by checked the other radio button?

20-Apr-07 1:14

You need to check Trace of the aaplication that will give where is the error or problem you are facing do one thing
1) make a change in the web.config by modifying Trace Enable=true.
2) type the URL of your application then type trace.axd at the last it will give detail of your application

Thanks and Regards
