[Solved] Access grid values on ItemCreated Event

[Kerry]

Hello, I am building the  onClick attribute of a HyperLink column within a RadGrid on the ItemCreated event, such as 

editLink.Attributes[

"onclick"] = "return ShowAttachForm();";

This calls a Javascript function to open a RadWindow.  I now need to pass parameters to the javascript function but I am having problems accessing the value of the other DataBoundGrid columns...it seems like the columns do not yet have a value.  How can I access the value of a column on the ItemCreated event of a RadGrid so I can do something like

 

editLink.Attributes[

"onclick"] = String.Format("return ShowAttachForm('{0}','{1}');", dataItem["JobNo"].Text, dataItem["ClientNo"].Text);

 

Thanks Kerry

Hello Kerry,

 Item Created event of the grid is fired before the item is data-bound. Thus no data will be available in the cells' text or input controls. So inorder to access a cell value, you can use the ItemDataBound event:
c#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
         {
            GridDataItem dataItem = (GridDataItem)e.Item;
            HyperLink editLink = (HyperLink)dataItem["HyperLInkColumnUniqueName"].Controls[0];
            editLink.Attributes["onclick"] = String.Format("return ShowAttachForm('{0}','{1}');", dataItem["JobNo"].Text, dataItem["ClientNo"].Text);
         }
    }

Thanks

Hi , thanks for the quick response, however I think I need to test what control I am trying to set the onclick attribute for, the code you gave me above causes an error trying to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.HyperLink.

THanks for the reponse but the code above causes an error trying to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.HyperLink. 

Thanks

Hello Kerry,

According to your initial post you wanted to add an onclick attribute to a HyperLinkColumn, thus the above code could be used for such a case. But since you are getting a cast error, it would be better if you could paste your aspx markup code here and also specify to which control do you want to add an onclick attribute.

Thanks
