Hi Telerik Team,

I have a RadGrid requirement that needs "InPlace" Editmode in which there need to be two dropdown columns one depends on other dropdown selection...

so i have seen a example in your site 

http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/validation/defaultcs.aspx

in this example when "Adding new Record" can i load data in second "Dropdownlist" depending on the first "Dropdownlist" selected value.
If so what is the best template column i can use to have an access on Dropdownlists.

Can u please guide me with correct approach how to obtain this requirement.

Its urgent...Please do respond

Thanks in Advance.

        }

Note : we are not able to get the itemtemplate's controls value on edit mode.
for that you can use datakey (shown in above code snippet) or take any other in editTemplate(Shown in Below code snippet).

<EditItemTemplate>
 
                        <asp:Label ID="lblNameEdit" Text='<%# Eval("Name") %>' runat="server"></asp:Label>
                        <asp:HiddenField ID="hfName" runat="server" Value='<%# Eval("Name") %>' />
 
 
                            <telerik:RadComboBox ID="cmbState" runat="server">
                            </telerik:RadComboBox>
                        </EditItemTemplate>


Let me know if any concern.

Hi, Jayesh thanks for ur reply. I have a concern here regarding "Label text" i am not evaluating it in the .aspx as u can see in my code...
I am setting it through code behind so i donot have an option to say "Datakey" i guess? because its not applicable in the context.
So do i have any other option???

Thanks

Hi Jaysh,
I have one more problem. I have attached a capture file which explains my problem, i am trying to add a new record to grid and i have couple of requied field validators when i select a item from "Source" combobox it should fire "SelectionChanged" event but its instead firing validators and not firing selection changed event.

I think i am missing some logic here firing the events. so can u please break the logic for me..

Its urgent plz respond.
protected void rgQueue_ItemCreated(object sender, GridItemEventArgs e)
       {
           if (e.Item is GridEditableItem && e.Item.IsInEditMode)
           {
               GridEditableItem item = e.Item as GridEditableItem;
                
               //Find the cell and the item to validate
               GridTextBoxColumnEditor sorteditor = (GridTextBoxColumnEditor)item.EditManager.GetColumnEditor("SortOrder");
               TableCell cell = (TableCell)sorteditor.TextBoxControl.Parent;
               RequiredFieldValidator validator = new RequiredFieldValidator();
               sorteditor.TextBoxControl.ID = "ID_for_validation";
               validator.ControlToValidate = sorteditor.TextBoxControl.ID;
               validator.ErrorMessage = "\n*Required";
               validator.ForeColor = Color.Red;
               validator.Display = ValidatorDisplay.Dynamic;
               cell.Controls.Add(validator);
 
               GridTextBoxColumnEditor queueeditor = (GridTextBoxColumnEditor)item.EditManager.GetColumnEditor("QueueName");

One more concern is when i hit "Edit" and Press "Update" it not even going to "Radgrid1_UpdateCommand" event...

Can u tell me waht may be reason for that...??

       {
           var editableItem = ((GridEditableItem)e.Item);
           var sortorder = (int)editableItem.GetDataKeyValue("SortOrder");
           //retrive entity form the Db

Thanku..
protected void rgQueue_UpdateCommand(object source, GridCommandEventArgs e)
       {
           var editableItem = ((GridEditableItem)e.Item);
           var Queue = (int)editableItem.GetDataKeyValue("Queue");
           var deleted = (Boolean)editableItem.GetDataKeyValue("Deleted");
           var sourceid = (int)editableItem.GetDataKeyValue("SourceID");
           //retrive entity form the Db
           using (EnabledDataContext db = new EnabledDataContext())
           {
               var queue = db.Queues.Single(n => n.Queue1 == Queue);
               if (queue != null)
               {
                   //update entity's state
                   editableItem.UpdateValues(queue);
                   try
                   {

Hi Velmurugan,

Can you please elaborate what is the exact problem you are facing? How to get selected values or how to set them while updating/inserting in database? Do you use TemplateColumn or FormTemplate?

Additionally, I suggest that you review the help article linked below:
http://www.telerik.com/help/aspnet-ajax/grid-insert-update-delete-at-database-level.html

Hello,

IList<RadListBoxItem> items = RadListBox1.SelectedItems;
       foreach (RadListBoxItem item in items)
       {
           string strtxt = item.Text;
           string strVal = item.Value;
       }
or
foreach (RadListBoxItem item in RadListBox1.Items)
       {
           if (item.Selected)
           {
               string strtxt = item.Text;
               string strVal = item.Value;
           }
       }


Thanks,

Hi Preeti,

Please try the following code snippet to fill the grid with values based on dropdownlist selection.

ASPX:
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSource1"
DataTextField="OrderID" DataValueField="OrderID" AutoPostBack="true" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
</asp:DropDownList>
<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" AllowPaging="true"
    OnNeedDataSource="RadGrid1_NeedDataSource" Visible="false">
    <MasterTableView DataKeyNames="OrderID">
        <Columns>
            <telerik:GridBoundColumn UniqueName="OrderID" DataField="OrderID" HeaderText="OrderID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="ShipCity" HeaderText="ShipCity" UniqueName="ShipCity" />
        </Columns>
    </MasterTableView>
</telerik:RadGrid>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Northwind_newConnectionString3 %>"
    SelectCommand="SELECT distinct [OrderID] FROM [Orders] Order By [OrderID] DESC">

C#:
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    String ConnString = ConfigurationManager.ConnectionStrings["Northwind_newConnectionString3"].ConnectionString;
    SqlConnection conn = new SqlConnection(ConnString);
    SqlDataAdapter adapter = new SqlDataAdapter();
    adapter.SelectCommand = new SqlCommand("SELECT OrderID, ShipCity FROM Orders where OrderID='"+ DropDownList1.SelectedValue +"'", conn);
 
    DataTable myDataTable = new DataTable();
 
    conn.Open();
    try
    {
        adapter.Fill(myDataTable);
    }
    finally
    {
        conn.Close();
    }
    RadGrid1.DataSource = myDataTable;
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    RadGrid1.Visible = true;
    RadGrid1.Rebind();
}

Thanks,
Princy
