Rad Grid Grouping

[Srinivas]

I am grouping data using Group by expressions and created a link button on a group header dynamically.

Also Added  command argument value Handler to that button in Item created and Item Databound event.

When I click on that button the values on the grid group header are disppearing and loosing the command argument values.

I need to get the command argument of buuton to make some changes to the data in the record.

Please help me on this.

Hello Srinivas,

I cannot reproduce the issue at my end. I suppose this issue arises when you are binding the grid using simple data binding. In order to implement advanced features like grouping, paging etc make sure that you are using Advanced data binding using NeedDataSource event. Check the following help documentation which explains more about this.
Advanced Data-binding (using NeedDataSource event).
Please elaborate your scenario if it doesn't help.

Thanks,
Shinu.

Hi Shinu,


Thanks for your responce.

I am binding the using need datasource event.

I don't have any issues while bind the data.

When I click on a buttong which I created from code behind values on group header are disappearing and command Argument I attached to the button is missions.

Please let me know if you have any solution for this.

Thanks,

Srinivas

Hello Srinivas,

Can you please verify that you set the CommandArgument value for the LinkButton in the group header inside the ItemCreated event of the grid? This event will be raised on each postback (see this topic for details concerning the RadGrid's comment event lifecycle) and thus the value should be available inside the ItemCommand handler of the control.

Best wishes,
