update control outside of nestedviewtemplate

[Brett Sturgis]

Hello.  I have a radgrid with a nestedviewtemplate set up so that another rad grid is shown when each row of data is expanded.  I have a button within each row on the grid inside the nestedviewtemplate, and that button needs to make a div visible that is outside of both radgrids.  However, I cannot for the life of me get the div to appear.  I currently have the following for the RadAjaxManager:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadGrid1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                <telerik:AjaxUpdatedControl ControlID="pnlAddEdit" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="RadGrid2">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid2" LoadingPanelID="RadAjaxLoadingPanel2" />
                <telerik:AjaxUpdatedControl ControlID="pnlAddEdit" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

Is this correct or do I need that second setting?  There is also a button on each row in the outer grid that makes the pnlAddEdit div visible.  The button on the outer grid does make the div appear, but the button on the inner grid does not.  What else do I need to do?

Hi Brett,

You do not need the second setting. Could you show how you are showing the div? Could you paste your entire aspx and code-behind?

Something else I am running into now is I am trying to bind the datasource for the RadGrid2 on the

 

RadGrid1_ItemCreated procedure.  However, I need to get a value from a specific column on the RadGrid1 in order to set the datasource for the RadGrid2.  However, I can only define the incoming value as follows:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    GridPagerItem gridItem = e.Item as GridPagerItem;

I cannot figure out how to get a value from a specific column from the GridPagerItem.  Is this possible?

Hi Brett,

I'd like to pay your attention to a couple of points:

1. You need to use only Advanced databinding vs Simple databinding, therefore, try reworking the code along the lines of the former one.

2. You must remove all declarative and programmatic ajax settings for the second grid and leave those just for the first one.

Tsvetoslav, I thank you for your help.  I now have a new problem.  I don't know if you will be able to tell what's going on just by looking at it, but i will attach my updated code as well.  The problem is now that when I click on one of the buttons in the nested RadGrid, for some odd reason the div at the top with the textboxes appears on the row that I click on.  I am not sure what's causing that.  Maybe you can look and see if you have any ideas.  Thanks.

Hi Brett,

I do not see your having reworked your code to use Advanced databinding - one of the requirements for that is to not bind the grid on PageLoad(). What happens I suspect is that upon clicking the row the grid posts back as you have EnablePostBackOnRowClick = true. And upon the post back your code behind makes the div visible. But still the main culprit is the Simple databinding that you are using all over the code-behind. Do make a careful review of the examples and the related help topics pointed to in my previous post.

All the best,
Tsvetoslav

Ok.  Thank you.  I will rework it to incorporate the advanced databinding.

[Brett Sturgis]

Ok.  Lol.  New problem.  I now have the expansions working correctly, but I want to just implement an editform so that when the user clicks "edit" on a row in the inside grid they can change the values in the textboxes then click the "update" link button and then update the record in the database.  However, right now when I click "update" I cannot figure out why neither the "RadGrid2_ItemUpdated" or "RadGrid2_UpdateCommand" procedures are being triggered.  Which one should be triggered?  I found an example on the telerik website that is similar to this, but the datasource is specified within the .aspx file.  I do not want to do that.  Does that have anything to do with why my events are not being triggered?  I just want to be able to get the correct event to be triggered so I can call an executesql in the codebehind and update the table in that manner.  I will attach my .aspx and codebehind.

Hi Brett,

I could not notice any reason for the described issue in your code - at least the troublesome code spots are commented out. Please, open up a formal support ticket and send a runnable sample of your implementation. I'll debug it and get back to you with the result. Thanks in advance.

All the best,
Tsvetoslav
