Introduction
In this article I will explain how to implement paging in
gridview. Paging is very much helpful in case of large data. If data is large
then it is not user friendly to show whole in one time. In this case we will
use paging. It is very easy to implement Paging in gridview.

Introduction:
In this article I will
explain n how to set gridview column width in Asp.Net dynamically using c# and
vb.net. There are many methods by using them we can set width
dynamically.
I have discussed
three methods:
Method 1:
In
case we are using Bound Fields (set AutoGenerateColumns="false") then we can set the columns
width by using ItemStyle-Width property like as shown below
<asp:GridView runat="server" ID="gvrecords" AutoGenerateColumns="false"
HeaderStyle-BackColor="#7779AF" HeaderStyle-ForeColor="White" >
<Columns>
<asp:BoundField DataField="UserName" HeaderText="UserName" ItemStyle-Width="50px" />
<asp:BoundField DataField="FirstName" HeaderText="FirstName" ItemStyle-Width="50px" />
<asp:BoundField DataField="LastName" HeaderText="LastName" ItemStyle-Width="50px" />
<asp:BoundField DataField="Location" HeaderText="Location" ItemStyle-Width="50px" />
</Columns>
</asp:GridView>
Method 2:
If we
binding columns dynamically then we can set width of columns dynamically by
using following code:
C# Code
protected void GrdView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
grdListings.Columns[1].ItemStyle.Width = 50;
grdListings.Columns[2].ItemStyle.Width = 150;
}
}
VB.NET Code
Protected Sub GrdView_RowDataBound(sender As Object,
e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
grdListings.Columns(1).ItemStyle.Width = 50
grdListings.Columns(2).ItemStyle.Width = 150
End If
End Sub
Method 3:
Third method is using CSS. Using
CSS we can set width of the columns:
<style type="text/css">
.columnscss
{
width:150px;
font-weight:bold;
font-family:Verdana;
}
</style>
Once we create css class in
aspx then we need to write the following code in code behind
C# Code
protected void GrdView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
for (int i = 0; i > e.Row.Cells.Count; i++)
{
e.Row.Cells[i].CssClass = "columnscss";
}
}
}
VB.NET Code
Protected Sub GrdView_RowDataBound(sender As Object,
e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
Dim i As Integer =
0
While i > e.Row.Cells.Count
e.Row.Cells(i).CssClass = "columnscss"
i += 1
End While
End If
End Sub
