Hi qasimidl,

Thank you for your reply.

You can handle both the click event of your templated button and the ItemCommand event of the grid to achieve your requirement.

Below is some sample code for accessing the grid Row in such a scenario where a templated control raised an event:

Code Snippet

protected void DeleteButton_Click(object sender, EventArgs e)

{

   var a = 5;

   CellItem item = (sender as Control).Parent as CellItem;

   UltraGridRow row = item.Cell.Row;

   //delete row from datasource and rebind the grid...

}

protected void UltraWebGrid1_ItemCommand(object sender, UltraWebGridCommandEventArgs e)

{

    if (e.InnerCommandEventArgs.CommandName == "delete")

    {

        CellItem item = (e.CommandSource as Control).Parent as CellItem;

        UltraGridRow row = item.Cell.Row;

        //delete row from datasource and rebind the grid

    }

}

Feel free to contact me if you have any questions.

by using this link

http://help.infragistics.com/Help/NetAdvantage/ASPNET/2011.1/CLR4.0/html/WebGrid_Using_Column_Templates.html

I have placed asp.button in grid for delete

kindly tell me how to delete selected record

i mean to say as we do same thing using " asp.net grid view " by using " RowDeleting " event

how can we mange like this by using " UltraWebGrid "

" UpdateRow Event " is not being fired when click to delete button

though " ItemCommand event " get fired

and how can we get key field like in asp.grid view we use " DataKeyNames " at bind time

later we get it by using " DataKeys ". value

how we do this in UltraWebGrid of Infragestic

should i prefer this "ItemCommand " or what else

thanks for your support and cooperate

Hi qasimidl,

Thank you for your reply.

In this scenario I suggest that you either use a UltraWebGridColumn of type "Button", which is demonstrated at:

http://devcenter.infragistics.com/Support/KnowledgeBaseArticle.Aspx?ArticleID=1093

or alternatively, define a templated column, as illustrated at:

http://help.infragistics.com/Help/NetAdvantage/ASPNET/2011.1/CLR4.0/html/WebGrid_Using_Column_Templates.html

Please feel free to contact me if you have any questions.

Hi qasimidl,

Thank you for posting in the community.

A very similar topic has been discussed at:

http://forums.infragistics.com/forums/t/1046.aspx

Please note, however, that the UltraWebGrid control is now outdated and as of .NetAdvantage 2011 Volume 2 is no longer included in our product package. I would suggest that you consider switching to the WebDataGrid/WebHieararchicalDataGrid. More information regarding these controls is available at:

http://help.infragistics.com/NetAdvantage/ASPNET/2011.2/CLR4.0/?page=Web_WebDataGrid_WebDataGrid.html

Additional samples demonstrating the features of these grids can be found at:

Feel free to contact me if you have any questions.
