Does this mean you got an error saying your formatting was wrong ? What does the HTML say ? Does this run, or not ?

It seems, the variable IncAdd is out of scope or not initialized or it is set with alpha numeric value.

Try this...

protected string IncAdd=string.Empty;
protected void Page_Load(object sender, EventArgs e)
{
    IncAdd = "17";//your logic goes here
}

Also cross check, what value you set into the variable. If it is alpha numeric, then cross check your code.

Hope this helps.
cheers

Solution 1

See, the error means what it says. It's for this reason that you should post the error message, if you can't understand it. IncAdd is a string. Make it an int, and it will work. That's what the message says.

Solution 3

IN SERVER SIDE CODE

TableHeaderCell obj = (TableHeaderCell)lTable1.Rows[5].FindControl("tempid");
obj.ColumnSpan = 17;
