How to bind DropdownProvider data(List) by sever side?

By the way,i want to create a Multi-Column WebDropDown as DropdownProvider .

I bind data by OnItemsRequested event,but it didn't worked.

protected void WebDropDown1_ItemsRequested(object sender, Infragistics.Web.UI.ListControls.DropDownItemsRequestedEventArgs e)
    {

        string value = e.Value.ToString();
        Infragistics.Web.UI.ListControls.WebDropDown wdd = sender as  Infragistics.Web.UI.ListControls.WebDropDown;
        wdd.CurrentValue = "Select a Product";

        //Set the drop-down container width
        wdd.DropDownContainerWidth = 500;
        //Create a new drop-do
        Infragistics.Web.UI.ListControls.DropDownItem productsItem = new Infragistics.Web.UI.ListControls.DropDownItem();
        //Set the text of the drop-down item
        productsItem.Text = "SOPActionCode";
        productsItem.Value = "SOPActionCode";
        //Add the drop-down item to the WebDropDown
        wdd.Items.Add(productsItem);

        //Creat a template with WebDataGrid
        wdd.ItemTemplate = new MultiColumnTemplate();

        MultiColumnTemplate obj = new MultiColumnTemplate();
        obj.InstantiateIn(wdd);
        wdd.ClientEvents.ValueChanging = "wddAction_ValueChanging";

    }

Hello EVEN CHEN,

Thank you for contacting us.

Please refer have a look at the forum thread below where a similar requirement have been discussed.

http://ko.infragistics.com/community/forums/t/60738.aspx

If Peter's suggestion is not suitable for you, I have attached a small sample that is showing how to make a Multi-Column DropDownEditor provider to edit WebDataGrid cells. When item from the grid(the one nested in the DropDownprovider) is choosen all cells in the row that is being edited are taking new values, depending on the selection of the grid in the provider.

If the sample do not fulfill your requirements, could you please send me isolated sample in order to show me the issue. This will be highly appreciated.

Hello,Zdravko Kolev,

Thanks for your replay and attachment.

But i have one question:

How to set value to DropDownEditor cell?

Below code from your attachment:

function templateGrid_RowSelectionChanged(sender, e) {

        ////Gets reference to the WebDropDownEditorProvider
        var dropdown = $find("WebDataGrid1_ctl01");

        //Gets the selected rows collection of the WebDataGrid
        var selectedRows = e.getSelectedRows();
        ////Gets the row that is selected from the selected rows collection
        var row = selectedRows.getItem(0);

        cellID = row.get_cell(0).get_value();
        cellFirstName = row.get_cell(1).get_value();
        cellLastName = row.get_cell(2).get_value();

        ////Sets the text of the value display to the first name column of the selected row
        dropdown.set_currentValue(row.get_cell(1).get_text(), true);

    }

I can't gets reference to the WebDropDownEditorProvider.

Hello,

Could you please add jQuery library to the website after the title section.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript"></script>

Also you can try to access the WebDropDownEditorProvider like:

var dropdown = ig_controls.WebDataGrid1_ctl01;

Looking forward to hearing from you.
