CP asked on 28 Sep 2016, 11:51 AM

I want to be able to intercept the insert action for a RadGrid and display a window allowing the user to select criteria which will then be carried over into the true editing control to pre-populate some of the data. I know that I can pre-populate controls in the ItemCommand event with hard-coded values by checking for InitInsertCommandName and locating the controls to populate.

Can I at this point open a radwindow containing the below and page. This window will allow the user to select from the 2 dropdowns & the textbox and on clicking the 'Select' button populate the grid with matching data from a database. On double clicking a row of data, that data will be sent back to the ItemCommand to populate the edit control.

Hello Robbie,

This is a highly custom requirement and there is no straight forward solution that we can provide, but you can go through the following help articles, which should help you achieving the desired result:

I should mention that you will have to use a custom button or external button for initiating your custom insert that will open the popup and not the built-in "Add new record" button of the RadGrid. Once you handle the double click event of the grid in the popup you could initiate a custom command through the main grid and use the following code to manually initiate the insert with the values:

Dictionary<string, string> initValues = new Dictionary<string, string>();

//fill the initValues

RadGrid1.MasterTableView.InsertItem(initValues);

Hope this helps.

Hi Konstantin,

I stared looking at this and created a small test app where i removed the in-grin insert new row option and created an external button to pop my selection window. The window seems to pop-up but immediately disappears. I've placed breakpoints in the selection page but nothing is hit so i'm not sure where its going astray ?
