Hello experts
i would like to know how to delete a row from a dataGrid (which is in edit mode), i am using paging and the built in edit, update, cancel methods.
I have been looking all over the posts most seem to be using databases and since i am using a XML file as my surce of data i am abit lost.
heres what i have in my delete event Handler..
private void dgStudents_DeleteCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
int rowToDelete = e.Item.ItemIndex;
dsStudents.student.Rows[rowToDelete].Delete();
//refresh datagrid control to show changes
BindData();
}
the rowToDelete int will get the row to delete, but when i run this and click on delete, i get a runtime error of "There is no Row at position 0"
Help please??
Cheers

I guess when page is posted back, you will loose this value. Have you checked the count of rows before issuing delete ?

You need to ensure that all the necessary files are copied across, web.config, bin directory etc.
Check IIS to ensure the correct version of ASP.NET is installed and configured correctly.

All files r copied properly.And the server is handled by some third party.I can only access it through ftp.I am uploading my project through ftp.Rest of the site under this server is working properly.Thank you.

Contact your third party and ensure the space that you bought to host your website has IIS and framework support

When a textbox column of a GridView is written out to the browser, the Id's of the text boxes are generated automatically by ASP.NET. The solution to your problem is letting the javascript calendar know the id of the textbox sitting next to it, in the same row of the grid.
You can do this in the RowDataBound event of the GridView which is fired as the data for each row of the GridView is bound.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
}
}Once you access the TextBox you can assign the onclick event to it with the appropriate client side textbox Id.
myTextBox.Attributes["onclick"] = "popUpCalendar(this, " + myTextBox.ClientId + ", \"dd/mm/yyyy\")";
Use the ClientId property on the server side to get the id of the textbox which will be written to the browser for that particular row. By examining the source of the web page you will see that the onclick for each row will have the correct id for the associated textbox.

if we keep gridview in loop to check for the values is the speed of the application get it slow
|
|
|
|
|
It depends on how many rows you have in the grid view.

I don't think looping 130 rows will be a performance overhead. What are you doing by looping ? Performance depends on many other factors.
