Slow page load with radgrid

[Alfonso]

Hi,

We have a RadGrid with the following configuration:

<telerik:RadGrid ID="Grid" runat="server"

       AutoGenerateColumns="false"

       Skin="Simple"

       AllowSorting="true"

       AllowFilteringByColumn="true"

       EnableHeaderContextMenu="true"

       EnableHeaderContextFilterMenu="true"

       OnNeedDataSource="Grid_NeedDataSource"

       OnItemDataBound="Grid_ItemDataBound"

       ViewStateMode="Disabled"

       AllowPaging="true" PageSize="500" AllowCustomPaging="true">

It has batch editing enabled, too.

It has about 30 columns, 20 of them are GridTemplateColumn with RadComboBox. When we have more than 100 rows, page load is very slow, and customer doesn't want us to have pagination.

Is there any way so we can speed up page load? It's a mandatory requirement for us.

Thanks in advance,

Alfonso

Hi,

Please, do you have any suggestion?

We are considering buying this control suite, but this is a blocking issue for us.

Thanks in advance,

Hi,

In order to speed up page load you should optimize the performance of both controls - grid and combo. For the RadGrid limiting the number of rows/columns will have the most impact on the performance. However, I suggest that you go through the following help link which elaborate on how to optimize RadGrid performance.
Client/server grid performance optimizations 

For the RadComboBox you could use Load On Demand with Web Service and enable the new Light-weight render mode.

Another option would be to use RadDropDownList in the grid instead of RadComboBox as shown in the online example below:
DropDownList in Grid
