have a radgrid with a nested radgrid containing child records. Everything works ok for purposes of data retrieval. Nested radgrid has in-place editing for data. When I click the edit button, the child grid disappears, leaving just the master grid in edit mode. Example shown in pic1 attached. When I click the pencil on any of the child records, that whole section disappears and the "update/cancel" buttons move up immediately under the wac pricing.

Code attached. Would like to know what I'm doing wrong, or, what I need to adjust to make it work. Thanks.

Hello Michael,

I have tested the provided code snippet on my end with sample data and everything is working as expected on my end.

Could you please try to temporarily disable the AJAX on your page and see if the same behavior is observable.

As a side note, please have in mind the RadGrid does not have "Name" nor "DataKeyNames" properties. "DataKeyNames" is a MasterTableView property. Furthermore, since you have ajaxified your grid, you should remove all nested AJAX settings from your RadAjaxManagerProxy:

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid_Products">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid_Products" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

For your convenience I have prepared a sample page, using your code snippet as reference, that works as expected on my end. Please refer to the attached files and see how it works on your side.

I am looking forward to your reply with additional information about the result after disabling AJAX.

Regards,
Konstantin Dikov

Greetings Konstantin,

I have used your sample, and as you said, it does work as expected.

However, as I am going against an SQL data source for my information, it is necessary for some modifications, to allow the child grids to get their correct data.

When I make these changes, I once again get symptom I previously describe. I click on master record pencil, I receive window with record and child tables populated correctly with data, but when I click pencil in child table to add record to child table, child table completely disappears.

Grid1.png shows screen when clicking on first master record pencil. Everything is populated correctly. Clicking on 1st pencil in WAC child grid yields grid2.png picture.

So, perhaps the issue is SQLdatasource, or how I am binding it? Or perhaps I should be handling a postback event when the child grid pencil is clicked? Here again is my new code based on your feedback, along with my code-behind.

Hello Michael,

I have examine again the provided code snippets and I was able to locate the root of the problem. Since you do not have SelectCommand in the SqlDataSource controls for your inner grids and due to the fact that the ItemDataBound event for the parent grid will fire only once while in edit mode, after a postback from the child occurs, there is no select command assigned for the SqlDataSource controls and no data is retrieved.

What you can do for your scenario is to handle the child grids server-side Load event for example, get reference to the parent GridEditFormItem and retrieve the data key, so you could assign the select command.

protected void RadGrid_WAC_Load(object sender, EventArgs e)

{

GridEditFormItem item = (sender as RadGrid).NamingContainer as GridEditFormItem;

String str = item.GetDataKeyValue("RowGUID_Key").ToString();

this.SqlDataSource_WAC.SelectCommand = "SELECT * FROM ProductAdministration_Pricing WHERE (RateIndicator ='W' AND Product_GUID = '" + str + "') ORDER BY EffectiveDate DESC";

this.SqlDataSource_WAC.Select(DataSourceSelectArguments.Empty);

//(item.FindControl("Inherit") as RadGrid).Rebind();

}

I have tested this with your setting and it is working as expected.
