How do we pass a parameter from a radgrid

[GarryP]

Hi,

I got image buttons on radgrids along with other data in the coloumns so when click on the image button i want it to pass a certain coloumn field in the form so i can use if statement call a function. I renamed it as outsource but it is not calling the commandName at all

rowInd = e.Item.ItemIndex
        comdName = e.CommandName

If comdName = "Outsource" Then
            MsgBox("done")
        End If

Is there a way to determine whats clicked on the radgrid button like i explained above?

Thanks

Hi GarryP,

I hope you are trying to access value from a GridBoundColumn on clicking an ImageButton in a GridButtonColumn. Here is the code snippet for the required scenario.

ASPX:

 <telerik:GridBoundColumn DataField="ProductName" HeaderText="ProductName" SortExpression="ProductName"  UniqueName="ProductName">
                        </telerik:GridBoundColumn>

 <telerik:GridButtonColumn ButtonType="imagebutton"  CommandName="Outsource"   ImageUrl="~/Images/Image1.gif" ></telerik:GridButtonColumn>

CS:

 protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "Outsource")
        {
            int rowindex = e.Item.ItemIndex;
            GridDataItem item = (GridDataItem)e.Item;
            string strTxt=item["ProductName"].Text.ToString();

        }
    }

Hi,

I converted the code to  VB.NET and it was giving an error saying "Error    1    'CommandName' is not a member of 'Telerik.WebControls.GridItemEventArgs'."

Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.WebControls.GridItemEventArgs)
        If e.CommandName = "Outsource" Then
            Dim rowindex As Integer = e.Item.ItemIndex
            Dim item As Telerik.WebControls.GridDataItem = DirectCast(e.Item, Telerik.WebControls.GridDataItem)
            Dim strTxt As String = item("ProductName").Text.ToString()

        End If
    End Sub

where as i used the code below, which was not doing anything.

 Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.WebControls.GridCommandEventArgs) Handles RadGrid1.ItemCommand

        Dim rowInd As Integer
        Dim comdName As String = ""

        rowInd = e.Item.ItemIndex
        comdName = e.CommandName

If comdName = "Outsource" Then
            MsgBox("done")
        End If
End Sub

and that was not giving errors but was not calling at all.

Thanks

Hi GarryP,

Have you set the ItemCommand EventHandler in the aspx?

ASPX:

  <telerik:RadGrid ID="RadGrid1" runat="server"  DataSourceID="SqlDataSource1" GridLines="None" OnItemCommand="RadGrid1_ItemCommand" OnNeedDataSource="RadGrid1_NeedDataSource"  >

Hi.

I have hyperlink buttons, which i added manually as the following code.

 <radG:GridTemplateColumn UniqueName="TemplateColumn">
                        <ItemTemplate>

            <a href="javascript:openPopup('WordAndSound.aspx?strCompanyNo=<%# Eval("CompanyNo")%>&strUserNo=<%#Eval("UserNo")%>&strSoundFile=<%#Eval("FileName")%>&strDocFileName<%#Eval("DocFileName")%>&strStatus=<%#Eval("Status")%>')">Play</a>
            <a href="javascript:openPopup('WordAndSound.aspx?strCompanyNo=<%# Eval("CompanyNo")%>&strUserNo=<%#Eval("UserNo")%>&strDictNo=<%#Eval("DictNo")%>&strDocFileName=<%#Eval("DocFileName")%>&strStatus=<%#Eval("Status")%>')">View</a>
              </ItemTemplate>
                        </radG:GridTemplateColumn>

The code above passes parameters to the other page page and the code below opens that page as a popup.

  <script type="text/javascript" language="javascript">
                function openPopup(strOpen)
                           {
                open(strOpen, "Info", "status=1, width=1000, height=700,resizable=1, scrollbars=1");
                        }
                </script>

I need to do the same as what the code above does in vb.net code.

such as if e.commandName = "play" then
I want it to open another pop up aspx page and pass the parameters to that page. I do not want to do redirect but open a new page. Do you know how can this be done?

Thanks

Hi GarryP,

You can check out the following Online demo where a similar scenario is implemented.

Here the Editcolumn is a HyperLinkColumn. A client side function to open a window is called on clicking the Hyperlink and a parameter(EmployeeID) is passed to it.

VB:

    Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs)
         If TypeOf e.Item Is GridDataItem Then
             Dim editLink As HyperLink = DirectCast(e.Item.FindControl("EditLink"), HyperLink)
             editLink.Attributes("href") = "#"

             'passing EmployeeID as a parameter
             editLink.Attributes("onclick") = [String].Format("return ShowEditForm('{0}','{1}');", e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("EmployeeID"), e.Item.ItemIndex)
         End If
     End Sub
