Hi,

I'm not sure if this is possible at all, but my intention is to use the gridview to display the data in it in two columns next to eachother. Lets say i have just a string in my databinding and 10 rows. Then i wish to display it like this:
row1 | row2
row3 | row4
row5 | row6
row7 | row8
row9 | row10

But as the gridview is making a table this cannot be done it seams. I have tried using itemtemplate and alternatetemplate but with no success as the gridview after each row inserts a new tr / td and ending thesame at the end.

Is there anyway this can be done with the gridview or do i need to use repeaters and make my own paging for that?

Thanks
Daniel Tiru

Yeah it is possible. Iterate through the results of your query. And convert each set of two rows into one. Then bind to the datatable. I didn't test the following code but you should get the idea.

<br />
DataTable dt = new DataTable();<br />
DataColumn dc = new DataColumn("RowOdd", Type.GetType("System.Int32"));<br />
DataColumn dc1 = new DataColumn("RowEven", Type.GetType("System.Int32"));<br />
dt.Columns.Add(dc);<br />
dt.Columns.Add(dc1);<br />
<br />
Int16 Count = 0;<br />
DataRow r;<br />
while (YourDataReaderObject.read())<br />
{<br />
      <br />
       if (Count = 0)<br />
       {<br />
        r = dt.NewRow();<br />
        r["RowOdd"] = dr.GetInt32(0);<br />
        Count = 1;<br />
        }<br />
        else<br />
        {<br />
         r["RowEven"] = dr.GetInt32(1);<br />
         dt.rows.add(r);<br />
         Count = 0;<br />
         }<br />
       <br />
}

I didn't get any requirements for the signature

Thanks, i get the general idee, i have used the click/drag/drop functions in VS with data but that should i figure out how to do...

But one thing more... as i in reality have more than one column, is this the right aproach?

DataTable dt = new DataTable();
DataColumn dc = new DataColumn("RowOdd", Type.GetType("System.Int32"));
DataColumn dc1 = new DataColumn("RowOdd1", Type.GetType("System.Int32"));
DataColumn dc2 = new DataColumn("RowOdd2", Type.GetType("System.Int32"));
DataColumn dc3 = new DataColumn("RowEven", Type.GetType("System.Int32"));
DataColumn dc4 = new DataColumn("RowEven1", Type.GetType("System.Int32"));
DataColumn dc5 = new DataColumn("RowEven2", Type.GetType("System.Int32"));
dt.Columns.Add(dc);
dt.Columns.Add(dc1);
dt.Columns.Add(dc2);
dt.Columns.Add(dc3);
dt.Columns.Add(dc4);
dt.Columns.Add(dc6);

I think that should be fine... (I realized when writing the code) Smile | :)

Thanks alot
Tiru

As an alternative you could use a DataList and use its RepeateColumn feature.

Hi, yes thats true, didnt know about that one... but the downside is that i then have to make my own pager... A bit to overkill for me at the moment i think.

Why the events for the Menu are not firing......?

Hi
I have a Menu (contains submenus) in my page which is used as just like tabs in VB, with which I want to make it work by hiding or unhiding the panels (panels contains the controls) through its (Menu) click event.

The problem is that, the click event is not raising. I have tried with the event handler
protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)
{} as I am using C#, but it did not work.
There is property added OnMenuItemClick="Menu1_MenuItemClick" in the menu tag in page1.aspx file.

How can I do this? Please suggest...

Im adding textboxes in my asp.net page on button click inside a panel,which i have placed in my page.

but the new control is getting created ,Im losing the old dyanmically create textbox.here is my code.

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

i = Convert.ToInt16(Session(ID))

Dim textbox As New TextBox

textbox.ID = "textbox" & i

textbox.Text = textbox.ID
textbox.Style("top") = "800px"

Panel1.Controls.Add(textbox)
i = i + 1
Session(ID) = i
End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Page.IsPostBack = False Then

Session(ID) = i
' MsgBox(Session(ID))
Else
' MsgBox("2")

End If

End Sub

dont know what is the mistake Im doing.Possibly its anything to do with Viewstate?

Thanks in advance

A textbox that is added dynamically, needs to be added on every postback, or it will disappear. It also needs adding prior to the load event, if you want to interact with it using viewstate, or get events from it.

There's no such thing as a 'cart variable'. You don't want to store the number of products anyhow, you want to calculate it based on the number of products that are in the cart.

Requirement in file upload control

Hi all,

When i select a file to upload in the file upload control, I am not able to see the file name in the control after i selects the file. For eg: Suppose if i select a file from desktop, then in the file upload control i can see only "C:\Documents and settings", where i am not able to see the file name by default.

Here my requirement is after i select the file to upload, I want the cursor to be get focused to the last in the control. So that I can see the file name as "\Desktop\Form.doc".

Thanks and Regards,
Hariharan C

For security reasons, you don't have granular control over the Input Type File control.

I don't think you can interact with the filename control in javascript, because it has access to the file system, and javascript does not. Also, it stops you from putting such a control on a page, using javascript to put a path like c:\windows\somesensitivefile.doc into it, and getting files from people's computers.

What's strange ? The requirement is not strange, and that it can't be done isn't strange, either.

What are you trying to achieve ? You'd start a new thread in the normal way, but if your main thread ends, then your page lifecycle ends and your page is served.

thanks! Confused | :confused:

You simply need to create img tags dynamically and add them to the Controls collection of a control in the page ( which will determine their location ). Or you can create them to include css which positions them.
