How to set Gridview column width dynamically in Asp.Net C#

In this article, I will show you how to set column- width of gridview in asp.net .We can use several methods to achieve it just like source code (grid view property), code behind(C#) and CSS.


First Method:-
we can set the columns width by using ItemStyle-Width property just like below :-

        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">


            <Columns>
                <asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="50px" />
                <asp:BoundField DataField="Contactno" HeaderText="Contactno" ItemStyle-Width="50px" />
                <asp:BoundField DataField="Brithday" HeaderText="Brithday" ItemStyle-Width="50px" />
            </Columns>
        </asp:GridView>

Second Method:-
We can call the columns’s width from code behind just like below :-
For this code we need to need to call RowDataBound.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {


            GridView1.Columns[0].ItemStyle.Width = 50;
            GridView1.Columns[1].ItemStyle.Width = 50;
            GridView1.Columns[2].ItemStyle.Width = 50;
        }

    }
Third method:-
We can set the column width using css but we call this call on only code behind because we can not directly call the css in column from source code and if we call on this gridview then it will be set whole gridview width not the columns. We can use this method like below:-
Source code:-

 <style type="text/css">
        .columnwidth
        {
            width: 50px;
        }
  </style>

Codebehind:-
protected void GridView1_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 = "columnwidth";
            }
        }
    }
