[Solved] radgrid IE error

[jason b]

I am sure I simply missed this config or such option when using the radgrid, but at this poitn I am not sure what the error is coming from.

I have a bound radgrid that shows up with its data fine in all browsers.  However, when i click the pageing function of the grid, it only works in FireFox and IE6.  In IE 7 and IE 8 (including quirks and compatibility modes) it emptys the grid whenever i try to click on any of the paging buttons. 

Is this a bug fix needed or do I need to do something to configure the control that i forgot to do?

Thanks!

Is there more data I need to provide to help adress this issue?

Hello Jason,

Can you confirm that you do not have any DataBind() calls for the grid?
Please have in mind that RadGrid paging is not supported with SimpleData binding. You should use advanced binding with NeedDataSource even handling or assign a data source control for the grid.

However, in case you use simple binding with DataBind() calls, consider switching to this type of binding to see whether this addresses the issue.

Thanks i will take a look at my databinding type today and see if the Grid has any calls missing, thanks!

[jason b]

ok, on a drop down list selection i bind the grid:

radGridOrderList.DataSource = orderList;

radGridOrderList.DataBind();

Session[

"GridSource"] = radGridOrderList.DataSource;

 

^ I put the datasource into session so that when the paging event is called i can pass in the datasource

protected

void radGridOrderList_PageIndexChanged(object source, Telerik.Web.UI.GridPageChangedEventArgs e)

 

{

radGridOrderList.DataSource = Session[

"GridSource"];

 

}

This all appears to work fin ein FireFox and IE 6, but in IE 7 or IE 8 the grib will not bind on the PageIndexChanged event.  Could it have something to do with the way IE7+ handles session info?

[jason b]

oops forgot, i am also using the needDataSource methos as well...

protected

void radGridOrderList_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

 

{

 

if (Session["GridSource"] == null)

 

{

}

 

else

 

{

radGridOrderList.DataSource = Session[

"GridSource"];

 

}

}

Hello Jason,

Please note that when using declarative the NeedDataSource event, RadGrid can automatically accommodate the appropriate database operations without the need for you explicitly handle any paging, sorting, grouping, and so on.

All the best,

Ok, then assuming i am using the NeedDataSource event properly, why am i loosing my datasource on the paging event?

[Pavlina]

Hi Jason,

I followed your scenario and prepared a simple working project which handles the desired functionality. Please check it out and let me know what is the difference in your scenario.

I hope this helps.

Looks like we might have just been loosing our session, i am investigating if it was due to the way we handeld the radgrid event...

Hi Jason,

If the issue persists, you can open a formal support ticket, and send us a small working project, demonstrating the problem. We will review it locally, and get back to you with additional information.
