add aggregate function to dynamically added column

[digish devassy]

I tried this:

if (e.Column.UniqueName.Contains("SomeColumn"))

{

GridBoundColumn item = (GridBoundColumn)e.Column;

item.Aggregate =

GridAggregateFunction.Avg;

}

@ column created step.

did not work.
Thanks in advance.

Hi,

Try the following code to achieve your scenario.
C#:

protected void RadGrid1_ColumnCreated(object sender, Telerik.Web.UI.GridColumnCreatedEventArgs e)
{
    if (e.Column.UniqueName == "UniqueName")
    {
        GridBoundColumn boundColumn = e.Column as GridBoundColumn;
        boundColumn.Aggregate = GridAggregateFunction.Avg;
    }
}

Thanks,
Princy.

SomeHow the unique name is not helping. Any other option please.

Hi,

I am not quite sure how you are adding the columns. Try the following approach to add aggregate function when adding columns dynamically.
C#:

GridBoundColumn boundColumn;
boundColumn = new GridBoundColumn();
RadGrid1.MasterTableView.Columns.Add(boundColumn);
boundColumn.DataField = "EmployeeID";
boundColumn.HeaderText = "EmployeeID";
boundColumn.Aggregate = GridAggregateFunction.Avg;

Thanks,
Princy.

I solved it by adding the column in tghe aspx page. this solved it.
Thanks. Both of the above help was good. I had found the same solution over the internet.

Thanks again.

the datasource to the grid is a pivoted table.. In this case, I tried the

protected void RadGrid1_ColumnCreated(object sender, Telerik.Web.UI.GridColumnCreatedEventArgs e)

{

if (e.Column.UniqueName == "UniqueName")

{

GridBoundColumn boundColumn = e.Column as GridBoundColumn;

boundColumn.Aggregate = GridAggregateFunction.Avg;

}

}

All I get e.Column.UniqueName is gridexpandcolumn. no gridbound column. when I check the column details in the grid. it says grid bound column.

I tried the prerender step. It is not working. I am not sure @ what step the aggregate is be added in the databound column.

Thanks in advance.

Hi Digish,

Based on the provided information it is hard to say what is causing the described issue on your end. Could you please post your aspx page markup with the related code behind? Thus we will be able to get more information about your scenario and provide you more to the point answer. Looking forward for your reply.
