VB.NEt:
Dim intColWidth As Integer = 25
GridView1.Columns(0).ItemStyle.Width = intColWidth
C#:
int intColWidth = 25;
GridView1.Columns(0).ItemStyle.Width = intColWidth;
2. Setting Column width as per Data-Content :
Write following piece of code in RowDataBound handler / event:
Note: Code is taken from MSDn for reference purpose only:
VB.NET:
Protected widestData As Integer
Protected Sub GridView1_RowDataBound(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)
Dim drv As System.Data.DataRowView
drv = CType(e.Row.DataItem, System.Data.DataRowView)
If e.Row.RowType = DataControlRowType.DataRow Then
If drv IsNot Nothing Then
Dim catName As String = drv(1).ToString()
Dim catNameLen As Integer = catName.Length
If catNameLen > widestData Then
widestData = catNameLen
GridView1.Columns(2).ItemStyle.Width = _
widestData * 30
GridView1.Columns(2).ItemStyle.Wrap = False
End If
End If
End If
End Sub
Protected Sub Page_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles Me.Load
widestData = 0
End Sub
C#:
protected int widestData;
protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
System.Data.DataRowView drv = default(System.Data.DataRowView);
drv = (System.Data.DataRowView)e.Row.DataItem;
if (e.Row.RowType == DataControlRowType.DataRow) {
if (drv != null) {
string catName = drv(1).ToString();
int catNameLen = catName.Length;
if (catNameLen > widestData) {
widestData = catNameLen;
GridView1.Columns(2).ItemStyle.Width = widestData * 30;
GridView1.Columns(2).ItemStyle.Wrap = false;
}
}
}
}
protected void  // ERROR: Handles clauses are not supported in C#
Page_Load(object sender, System.EventArgs e)
{
widestData = 0;
}
