More details as listed below.

I am getting the error "cannot convert from infragistics.web.ui.gridcontrols.summaryrowsetting to string". Column is defined as integer, not sure why I am getting this error.

ColumnSummaryInfo BNCartonsSummary1 = new ColumnSummaryInfo();

BNCartonsSummary1.ColumnKey = "DDCARG";

BNCartonsSummary1.Summaries.Add(SummaryType.Sum);

wbgdata1.Behaviors.SummaryRow.ColumnSummaries.Add(BNCartonsSummary1);

Columns are added manually as listed below:
tblShipment = new DataTable("Shipment");
tblShipment.Columns.Add(new DataColumn("Cartons", typeof(int)));

tc = wbgdata1.Columns["DDCARG"] as TemplateDataField;

if (tc == null)

{
tc = new TemplateDataField();

tc.Key = "DDCARG";

tc.ItemTemplate = new PlaceHolderTemplate();

this.wbgdata1.Columns.Add(tc);

}

Please help.

Thanks.

Denis,

Thanks for the update.

I have a templated column with lnk button and I am trying to get the summary for the templated column. How do change the DataType for templated column?.

Please see the sample code as listed below.

public void GetData()
{
    DataTable tblShipment = new DataTable("Shipment");
    tblShipment.Columns.Add(new DataColumn("DDC", typeof(int)));
 
 TemplateDataField tc = WebDataGrid1.Columns["DDC"] as TemplateDataField;
 if (tc == null)
 {
  tc = new TemplateDataField();
  tc.Key = "DDC";
  tc.Header.Text = "Expected In Store";
  tc.ItemTemplate = new PlaceHolderTemplate();
  tc.Width = Unit.Pixel(60);
  this.WebDataGrid1.Columns.Add(tc);
 }
 
    DataRow r = tblShipment.NewRow();
    r["DDC"] = 30;
    tblShipment.Rows.Add(r);
    WebDataGrid1.DataSource = tblShipment;
 
    //Bind the Dataset to the web grid
    WebDataGrid1.DataBind();
}

       
       
private class PlaceHolderTemplate : ITemplate
        {

            #region ITemplate Members

            public void InstantiateIn(Control container)
            {
 
                GridRecordItem gri = (GridRecordItem)((Infragistics.Web.UI.TemplateContainer)(container)).Item;

                switch (gri.Column.Key)
     {
                        case "DDC":
                                    LinkButton lnk = new LinkButton();
                                    lnk.ID = "LinkButton1";
                                    lnk.Attributes.Add("onClick", "ClientClick();");
                                    container.Controls.Add(lnk);
                                    break;
     }
   }
  }
  
  
protected void WebDataGrid1_InitializeRow(object sender, Infragistics.Web.UI.GridControls.RowEventArgs e)
  {
  LinkButton lnk;
 
  lnk = (LinkButton)e.Row.Items.FindItemByKey("DDC").FindControl("LinkButton1");
                   
                   
                    if (lnk != null)
                    {
                       
                        lnk.Text = tblShipment.Rows[e.Row.Index][0].ToString();
 
                        lnk.Attributes["onclick"] = "BLOCKED SCRIPTbuttonClick('" + lnk.Text + "');";
                       
                        lnk.Attributes["onmouseover"] = "this.style.color=\'#ff0000\'";
                        lnk.Attributes["onmouseout"] = "this.style.color=\'#000000\'";
                        lnk.ForeColor = Color.Black;
                        lnk.Click += new EventHandler(this.lnk_Click);
                      

                    }
 }

Thanks for your help.

Denis,

I tried to use type property, but not successful. Please send me the sample code demonstrating type property with TemplateDataField.

Thanks.

Denis,

summary value is getting doubled for the regular unbound column, please review the sample code attached.

Denis,

Also, is it possible to remove the caption sum = ?.

Thanks.

Denis,

Thank you for the sample code. I am able o get the summary of the template column using your code, but I noticed that summary value is getting doubled for the unbound column. Please review the sample code and advise.

Thanks.
