Expand Button in MasterTable not expanding

[Amy]

Hi!  I have a RadGrid with a MasterTable and a DetailsTable.  The MasterTable has a column in it with the 'expand' button.  However when I click on the 'expand' button nothing happens. 

I've checked to ensure the 'GridRelationFields' have the correct values for the 'DetailKeyField' and the 'MasterKeyField'.  The MasterTable and the DetailsTable both have columns for these values.

Could someone provide suggestions for troubleshooting?  I have this same logic working on another page in our web application, but must be missing something for this particular page.

Thanks!

Hello Amy,

If you are using GridButonColumn, check whether you have set appropriate CommandName for Exapnd/Collapse button.

ASPX:

<telerik:GridButtonColumn ButtonType="PushButton" Text="Expand" CommandName="ExpandCollapse">
</telerik:GridButtonColumn>

Or you can use GridExpandColumn for this purpose.

<telerik:GridExpandColumn ButtonType="PushButton">
</telerik:GridExpandColumn>

Thanks,
Princy.

Princy, thank you for your suggestion.  However, I'm still not able to get the 'expand' button to work.  I'm guessing I don't have something linked correctly between the MasterTable and the DetailTable, but just can not seem to figure out what it may be.  Any other suggestions?

Thanks!

Princy, I was able to get the issue resolved.  I think the cause may have been the session parameter I specified in the sqldatasource was not the same value as the input parameter for the stored procedure.  Once I modified the stored procedure input parameter to be the same as the session parameter in the sqldatasource I was able to get the rows to expand in the grid.

Thank you as always for all your help!!
