Hello Friends !!

How to Merge cells in Asp.net GridView Footer ?
This project to used to enter students Marks using Gridview footer
am working on gridview, This gridview has 6 columns.
In this gridview I have Textboxes and a add button in footer to add the records. This is working fine till here.
Now I want to add one more Large Textbox in footer to Enter the Remarks for this particular record.

So, My requirement is, this textbox should cover all the 6 columns,(I mean it should Merge)
It should Merge 6 columns into one row
This is my design code.

hello !!
Try this,

<pre lang="vb"> If (e.Row.RowType = DataControlRowType.Footer)
{
GVUserEntry.FooterRow.Cells(0).ColumnSpan = 7
GVUserEntry.FooterRow.Cells.RemoveAt(1)
GVUserEntry.FooterRow.Cells.RemoveAt(2)
GVUserEntry.FooterRow.Cells.RemoveAt(3)
GVUserEntry.FooterRow.Cells.RemoveAt(4)
GVUserEntry.FooterRow.Cells.RemoveAt(5)
GVUserEntry.FooterRow.Cells.RemoveAt(6)
}

</pre>


Thanks & Happy Coding..

.aspx file is
XML
<body>
    <form id="form1" runat="server">
    <div>
    <asp:GridView ID="GridView1" ShowFooter="True" runat="server" Width="421px"
            onrowdatabound="GridView1_RowDataBound" >
            <Columns>
                <asp:TemplateField>
                <ItemTemplate>

        </asp:GridView>
    </div>
    </form>
</body>

.cs file is as follow...in GridView1_RowDataBound in cell i textbox is added dynamicaly runtime by merging secound column in it
protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
            bind();

             
    }
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        GridViewRow gvr = e.Row;
        if (e.Row.RowType == DataControlRowType.Footer)
        {
            int index = GridView1.Rows.Count;
            GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Footer, DataControlRowState.Normal);
            TableCell cell = new TableCell();
            TextBox txt = new TextBox();
            txt.Width = 350;
            cell.Controls.Add(txt);
            TableCell cell2 = new TableCell();
            row.Cells.Add(cell);
            row.Cells.Add(cell2);
            row.Cells[0].ColumnSpan = 3;
            row.Cells[1].Visible = false;
            GridView1.Controls[0].Controls.Add(row);

         
        }
    }

    private void bind()
    {
        DataTable table = new DataTable();
        table.Columns.Add("name");

        DataRow dr = table.NewRow();
        dr["name"] = "rowa";
        table.Rows.Add(dr);

        DataRow dr2 = table.NewRow();
        dr2["name"] = "rowa";
        table.Rows.Add(dr2);

        this.GridView1.DataSource = table;
        this.GridView1.DataBind();

C#
if (e.Row.RowType = DataControlRowType.Footer)
{
    // Set the span
    GVUserEntry.FooterRow.Cells(0).ColumnSpan = 7

    // Remove the spanned columns. *Don't* remove
    // 1, then 2, then 3 etc as you'll eventually
    // overflow the bounds!
    for(int i = 0; i < 6; i++)
        GVUserEntry.FooterRow.Cells.RemoveAt(1)
}
