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
