templated column with checkbox at run time + add events
posted

Hi

we are using ultrawebgrid 10.3 with c#. We are creating templated columns at run time with controls. In this case, it is checkbox. How can I add an server side event to fire when control is created. code is like this:

 

 

 

 

 

 

 

protected

 

class PlaceCheckTemplateForDynamic : ITemplate

{

 

 

 

public const string  KEY_NAME = DYNAMICCOL_KEY;

 

 

public void InstantiateIn(System.Web.UI.Control container)

{

 

 

CellItem cellitem = ((CellItem )(container));

 

 

CheckBox cb = new CheckBox();

cb.ID =

"chkDynamic";

cb.AutoPostBack =

true;

cb.CheckedChanged += new EventHandler(chkDynamic_CheckedChanged); (not working)

cellitem.Controls.Add(cb);

How can I add the event.

Thanks,

Prathiba

    Hello Prathiba,

     

    Thank you for posting in our community. You need to instantiate the control during the Page_Init. Put this code in there:

     

    

    TemplateDataField tempColumn = new TemplateDataField(true);
    

    tempColumn.Key = "TemplateColumn1";
    

    tempColumn.Header.Text = "TemplateColumn";
    

    tempColumn.Width = Unit.Pixel(20);
    

    this.WebDataGrid1.Columns.Add(tempColumn, true);
    

     
    

    TemplateDataField templateColumn1 = (TemplateDataField)this.WebDataGrid1.Columns["TemplateColumn1"];
    

    templateColumn1.ItemTemplate = new CustomItemTemplate();
    

     

     

    Now the event should be handled.

     

    I hope this helps.

     

    Sincerely,
