ImageClickEventHandler not firing

[Andrew]

Hi

I am trying to add an ImageClickEventHandler onto an imagebutton.
Althought i cant get it to fire. I am doing this within the ItemDataBound event of the grid . I tried changing EnableViewState to false, but that made no difference.

Any ideas would be greatly appreciated

    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        ImageButton imgBtnHolder = new ImageButton();

       if (e.Item is GridDataItem)
        {
            switch (e.Item.OwnerTableView.Name)
            {

                case "Vis":
                    {
                        GridDataItem item = (GridDataItem)e.Item;



                        imgBtnHolder = ((ImageButton)item["colDelete"].FindControl("imgDelete"));
                        imgBtnHolder.ImageUrl = "data_delete.gif";
                        imgBtnHolder.AlternateText = "Delete";
                        imgBtnHolder.OnClientClick = "return confirm('Are you sure you want to remove this');";
                        imgBtnHolder.CommandName = "Delete";
                        imgBtnHolder.CommandArgument = "cccc";
                        imgBtnHolder.Click +=new ImageClickEventHandler(imgBtnHolder_Click);

                        break;
                    }


            }

        }
    }


    void imgBtnHolder_Click(object sender, ImageClickEventArgs e)
    {
        throw new NotImplementedException();
    }

Thanks

Hi Greg,

Try adding the Click eventhandler for the ImageButton in the ItemCreated event and see whether it is working.

CS:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
    {
         ImageButton imgBtnHolder = new ImageButton();

       if (e.Item is GridDataItem)
        {
            switch (e.Item.OwnerTableView.Name)
            {

                case "Vis":
                    {
                        GridDataItem item = (GridDataItem)e.Item;



                        imgBtnHolder = ((ImageButton)item["colDelete"].FindControl("imgDelete"));
                        imgBtnHolder.ImageUrl = "data_delete.gif";
                        imgBtnHolder.AlternateText = "Delete";
                        imgBtnHolder.OnClientClick = "return confirm('Are you sure you want to remove this');";
                        imgBtnHolder.CommandName = "Delete";
                        imgBtnHolder.CommandArgument = "cccc";
                        imgBtnHolder.Click +=new ImageClickEventHandler(imgBtnHolder_Click);

                        break;
                    }


            }

        }
    }

void imgBtnHolder_Click(object sender, ImageClickEventArgs e)
    {
        throw new NotImplementedException();
    }

Thanks

Hello Llaria,

Give a try with the following code snippet.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

    {

       if (e.Item is GridDataItem)

        {

            GridDataItem item = (GridDataItem)e.Item;

            ImageButton imgBtnHolder = new ImageButton();

            imgBtnHolder.ID = "imgBtnHolder";

            imgBtnHolder.ImageUrl = "data_delete.gif";

            imgBtnHolder.CommandName = "Delete";

            item.Cells[2].Controls.Add(imgBtnHolder);//adding control to appropriate cell

            imgBtnHolder.Click+=new ImageClickEventHandler(imgBtnHolder_Click);

        }  

    }
  void imgBtnHolder_Click(object sender, ImageClickEventArgs e)
    {
       
    }

Thanks,
Princy.
