Client Databind Fails/Hangs with DataFormatString {0:g}

I have a RadGrid where one of the columns binds to a date/time value. I use a GirdDataBound column and it binds correctly on the server. Using the same source for the data, this fails when I try to bind on the client. It shows the first record, then just stops. The lines that follow in the Javascript function do not execute.

I removed the DataFormatString and it worked.

To work around this, I changed the column to a string and formatted it before sending it out to be bound.

I know I'll trip on this again some day (probably soon), so I'd like to get a resolution.

Thanks.

How to Check all the treeNodes by default?

Hi all,

Is there any way i can make all the nodes of the treeview checked by default other than looping through the nodes and setting each node property

Checked=true;

I dont want to unnecassary loop through the node collection to set each node property.

There should be easy way of doing this by setting simple property for the entire treeview.

Oh also I dont have these properties

TriStateCheckBoxes="true" CheckChildNodes="true" as it is not supported in my version of rad treeview

Break point not hit on update or insert command

Hello,

I am using the radgrid with a web user control for the modal popup. I switched the save buttons from regular asp.net buttons to the radbuttons and now my break points won't get hit and I believe the method isn't even being hit when the save button is pressed. My markup is below. The methods do have the handles statement. Is there something I am missing?

<telerik:RadButton ID="updateButton" runat="server" Text="Save" Width="75px" CommandName="Update"

Visible='<%# Not (TypeOf DataItem Is Telerik.Web.UI.GridInsertionObject) %>'

Skin="Outlook" CausesValidation="false">

</telerik:RadButton>

<telerik:RadButton ID="insertButton" runat="server" Text="Save" Width="75px" CommandName="PerformInsert"

Visible='<%# (TypeOf DataItem Is Telerik.Web.UI.GridInsertionObject) %>' Skin="Outlook"

CausesValidation="false">

</telerik:RadButton>

Thank you for your help.

P.S. I should also add that other break points work. The ItemCommand method breaks properly and all the others do too.

Grid + RadWindow problems

Hi,

I have a radGrid and I want to implement the following functionality:

1. When a single left click is performed on a row a postback occurs so I can enable a toolbar.

2. When the toolbar button is clicked a radWindow is opened with some parameters relating to the currently selected row.

In the main this all works fine however there is an issue - after the first postback and the window is opened and then closed any subsequent postbacks reopens the previously closed window.

I've set DestroyOnClose to true for the window but this doesn't seem to make any difference.

Thanks in advance for any assistance,

Kirk

Filter values and actual query against the db

Hi:

I am creating a filtered grid and I am concerned about performance. My default query against the table has a top 200 attribute. I went into 'Sql Query Profiler' and the filter did not appear. So, are you only applying the filter against the output dataset? In which case the top 200 will not work. How can I have the actual db query limited?
