Hi Ratan,

I guess you want to set LinkButton's text same as next column in grid. If so you can set the DataTextField as next column's DataField as shown below.
ASPX:

    . . .
    <telerik:GridButtonColumn UniqueName="Link" DataTextField="CustomerID" >
    </telerik:GridButtonColumn>
    <telerik:GridBoundColumn DataField="CustomerID" HeaderText="CustomerID" SortExpression="CustomerID"
        UniqueName="CustomerID">
    </telerik:GridBoundColumn>
    . . .

You can also accomplish the same from code behind.
CS:

    protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            String str = item["CustomerID"].Text; // Access the text of second column
            LinkButton lnkButton = (LinkButton)item["Link"].Controls[0]; // Get the linkbutton control
            lnkButton.Text = str; // Set the text
            if(str.ToLower() == "leave") // Check for condition
            {
                lnkButton.ForeColor = System.Drawing.Color.Red;
            }
        }
    }

Hello Ratan,

You can pass the LinkButton's text as url parameter and get the value in PageLoad event. Here is the code for setting the url parameter in ItemDataBound event.
C#:

    protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            String str = item["CustomerID"].Text;
            LinkButton lnkButton = (LinkButton)item["Link"].Controls[0];
            lnkButton.Text = str;
            lnkButton.PostBackUrl = "Redirect.aspx?ID="+ lnkButton.Text; // Set the LinkButton text as url parameter
            if(str.ToLower() == "leave")
            {
                lnkButton.ForeColor = System.Drawing.Color.Red;
            }
        }
    }

And in the PageLoad event of second page, get the value as shown below:
C#:

    protected void Page_Load(object sender, EventArgs e)
    {
        string id = Request["ID"];
        Response.Write(id);
    }

Shinu.
