Passing Multiple Command Arguments In Gridview.

Suppose you have gridview with data and it contains a link which shows Class-Sub Departments.Gridview also contains class-subject id and Practical-Subject Id. Now you want to open new window which contains both id`s ie, class-subject id and Practical-Subject Id. For this purposes, following coding is usefull.

<asp:GridView ID="GridView1" runat="server" SkinID="GridView"

onrowcommand="GridView1_RowCommand" >

<Columns>

                               

<asp:TemplateField HeaderText="Subject" SortExpression="classscheduled">

<ItemTemplate>

<asp:LinkButton ID="Hyper" runat="server" Text='<%# Bind("ClassSubDepartmentName") %>' onclick="Hyper_Click" CommandName="Link" CommandArgument='<%# Eval("ClassSubject")+ ","+ Eval("practicleSubject") %>'></asp:LinkButton>

</ItemTemplate>

</asp:TemplateField>                                                         

                               

</Columns>

<HeaderStyle BackColor="Blue" ForeColor="White" />

</asp:GridView>

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)

{

string[] commandArgs = e.CommandArgument.ToString().Split(new char[] { ',' });

if (e.CommandName == "Link")

{

ClientScriptManager script = Page.ClientScript;

ScriptManager.RegisterStartupScript(this, GetType(), "show", "openWin('" + commandArgs[0].ToString() + "', '" + commandArgs[1].ToString() + "')", true);

Session["ClassSubId"] = commandArgs[0].ToString();

Session["PracticalSubId"] = commandArgs[1].ToString();

// Here you found both id`s ie, class-subject id and Practical-Subject  //Id and store in Sessions. Use these session`s value in second page.

}

<script type="text/javascript">

function openWin(a ,b)

{

var ClassSubId = a;

var PracticalSubId = b;

              

window.open('YourPageName.aspx?SD=' + ClassSubId + '&PSD=' + PracticalSubId , 'CreateWindow3', '');

}

         

</script>

On second form, retieve both id`s from following code:

int ClassSubId= Convert.ToInt16(Request.QueryString["SD"].ToString());

int PracticalSubId= Convert.ToInt16(Request.QueryString["PSD"].ToString());
