Hi,

This is my first posting in this forum.

I am currently having an issue where by a DataTable returned from the Database Query 'may' contains exponents and when I attempted to Bind the table [Basic Binding]:


Please refer to attached for a simple snapshot as to data for binding that is generating the error.

I have tried to identify the exact RadGrid Events where this exception is generated but I was unable to determine the event.

Is there a way for the Radgrid to handle these values (via settings) or do I have to handle it manually in the correct Radgrid event?

Thanks.

The Exception is:

System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.FormatException: Input string was not in a correct format.

I have an issue with IIS 7.5. Any web page with Telerik controls pops up a windows authentication login box and it fails to authenticate and results in error '401 - Unauthorized.  Access is denied due to invalid credentials'. All other pages without Telerik controls works fine. It looks like using Host Name for the website in IIS  is creating the problem.

Environment:
Telerik        :  RadControls for ASP.Net JAAX Q2 2011 SP1
OS Version : Windows 2008  R2 
OS Version :  64bit
IIS Version  ; IIS 7.5
.Net Framework : 4.0
Authentication : Windows Integrated
App pool(mode) : Integrated
HostName : xxxxx-stg.xxx.com


Below is the web.config section



Thanks in advance.

Hi,
I want my grid to be "load on demand" so don't want it populating on PageLoad. How can I tell it to not populate until I explicitly call Rebind() ?

Cheers

I have a scheduler where each appointment has an export option, as well as the scheduler as a whole.

If I export all the appointments on the scheduler, everything works.

If I export a recurrence master, that works too.

If I try and export a single recurrence instance though, all I get is this ...
and if I try and import it in to Outlook it complains, unsurprisingly.

What am I missing?

I have placed a link button into commandItemTemplate of Grid so that i can add rows to end of grid on server side. But I am observing that whenever there is a postback after clicking link button, the same link button displyed next to the existing Link button.
Clicking the newly created link button does not fired the server side event.
The thing that i have done with grid is that all the rows of grid are in ediable form.


Thanks and Regards

With HTML5 gaining so much popularity, are there any plans to incorporate HTML5 with RAD asp.net ajax controls in the up comming versions. So that the asp.net ajax controls would start utilizing the capabilities of html5, like html5 forms, hardware capabilities(SVG) and render tags all which would be supported by the executing browser. Waiting for your reply as a lot more depends on that.

We've seen our radGrid where page numbers 1 and 2 are highlighted and not clickable,
almost as if we were on both page 1 and 2.
Screen shot attached

Its happened a couple times but were not able to recreate it. We dont have much to go on but do have a screenshot to prove it.

Has anybody else ever seen this behaviour?

Hi,

I've a RadToolBar in RadListView's itemTemplate.
My problem is that; When I give CommandName to RadToolBarButtons. listview's ItemCommand function doesn't catch it.

..
<telerik:RadToolBar ID="tb" runat="server">

<Items>

<telerik:RadToolBarButton runat="server"  text="test" CommandName="Edit"></telerik:RadToolBarButton>

</Items>

</telerik:RadToolBar>
..

only if I give a buttonClick command to RadToolBar, tb_ButtonClick function can do it..

<telerik:RadToolBar ID="tb" runat="server" OnButtonClick="tb_ButtonClick">

<Items>

<telerik:RadToolBarButton runat="server"  text="test" CommandName="Edit"></telerik:RadToolBarButton>

</Items>

</telerik:RadToolBar>

My Question is that; Is there any way to catch ListView_ItemCommand function by not using RadToolBar ButtonClick ?


Thanks
Sincerely,
Caglar DUMAN

Dear Telerik Team,

I am using Rad Grid and have following columns in my Grid.

<Columns>
            <telerik:GridClientSelectColumn UniqueName="CheckboxSelectColumn" ItemStyle-HorizontalAlign="Left">
                <HeaderStyle Width="25px" />
                <ItemStyle HorizontalAlign="Center" />
            </telerik:GridClientSelectColumn>
            <telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn">
                <HeaderStyle Width="30px" />
                <ItemStyle HorizontalAlign="Center" />
            </telerik:GridEditCommandColumn>
            <telerik:GridCheckBoxColumn DataField="ysnPrimaryAddress" ConvertEmptyStringToNull="true"
                DefaultInsertValue="false" HeaderText="Primary" SortExpression="ysnPrimaryAddress"
                UniqueName="ysnPrimaryAddress" HeaderTooltip="Primary" Visible="false">
                <HeaderStyle Width="50px" />
                <ItemStyle HorizontalAlign="Center" />
            </telerik:GridCheckBoxColumn>
            <telerik:GridBoundColumn DataField="strPrimaryAddress" HeaderText="Primary" SortExpression="strPrimaryAddress"
                UniqueName="strPrimaryAddress" HeaderTooltip="Primary" CurrentFilterFunction="Contains">
                <HeaderStyle Width="90px" />
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="strAddressType" HeaderText="Address Type" SortExpression="strAddressType"
                UniqueName="strAddressType" HeaderTooltip="Address Type" CurrentFilterFunction="Contains">
                <HeaderStyle Width="90px" />
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="strAddress1" HeaderText="Address 1" SortExpression="strAddress1"
                UniqueName="strAddress1" HeaderTooltip="Address 1" CurrentFilterFunction="Contains">
                <HeaderStyle Width="125px" />
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="strAddress2" HeaderText="Address 2" SortExpression="strAddress2"
                UniqueName="strAddress2" HeaderTooltip="Address 2" CurrentFilterFunction="Contains">
                <HeaderStyle Width="125px" />
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="strStreet" HeaderText="Street" SortExpression="strStreet"
                UniqueName="strStreet" HeaderTooltip="Street" CurrentFilterFunction="Contains">
                <HeaderStyle Width="125px" />
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="strCity" HeaderText="City" SortExpression="strCity"
                UniqueName="strCity" HeaderTooltip="City" CurrentFilterFunction="Contains">
                <HeaderStyle Width="90px" />
            </telerik:GridBoundColumn>
        </Columns>

I really don't understand why Filter Menu doesn't show all items. Specially items like Contains, Starts With ,Ends With, Is Empty doesn't appear. Please advise. Thank you in advance for any assistance.
