View 5 RepliesI am binding a table to a gridview in asp.net as such
grdIssues.DataSource = mdtIssues;
grdIssues.DataBind();
The problem is I cannot then control the column width, asp.net seems to decided on it's own what width each column should be. Methods such as
grdIssues.Columns[0].ItemStyle.Width = 100;
grdIssues.Columns[1].ItemStyle.Width = 100;
don't work because the columns are created dynamically. I cannot believe there isn't a way to do this short of manually creating each column and filling each row.

I'm loading data from my database into a DataTable, and one of the columns is a date field.
[Code]....
I'd like to format that column so that instead of containing a full date, it will be formatted like "MM/DD/YYYY".
I've tried looping through each row in the table and changing the cell for that column, but I get an error saying that the string isn't a valid DateTime object.
I tried changing the column DateType to a string, but I get an error saying I can't change the DateType after the table is filled.
How can I do this? This seems like such a simple thing, but I'm having so much trouble with it.
I have a datatable that looks as follows:
Make,Ford,0
Model,Fusion,0
Year,2010,0
Make,Ford,1
Model,Focus,1
Year,2010,1
I'd like to loop through each row and replace all the values of the same type in the 3rd column with a different value.
So for example I would change all the 0 to 1234 and all the 1 to 1235. So I'd end up with:
Make,Ford,1234
Model,Fusion,1234
Year,2010,1234
Make,Ford,1235
Model,Focus,1235
Year,2010,1235
Whats the best way to do that ?
