Parameter is NOT valid. Check image is good before displaying

Hi,
    Recently, I found an issue that when an image is corrupted, and we try to assign it to RadBinaryImage, we get error "Parameter is not valid". Thats OutOfMemory exception, seems .NET can't load image properly then. However, this cause ASP.NET application to throw an "unhandled" exception.

   I wonder, if it was possible for telerik component to validate the image as it was assigned to it (like DataValue property) and throw an exception to indicate that assigned value is NOT a valid image. Currently, I have to load image, and if loads successfully, then I use my routine to convert the image to bytes and assign to DataValue property.

   Though I see many threads on this topic "Parameter is not valid", as per I know, its "mysterious" ASP.net message and most of the time, caused by OutOfMemory exception. I wonder if this "check of validity of image" should be implemented in other controls of telerik, like reporting etc.

   Thanks,
   Sameers

RadGrid questions

Hi

I have a RADGrid with one button column and rest bound columns as follows;

<telerik:RadGrid ID="DocsList" runat="server" AllowPaging="True" GridLines="None"

OnNeedDataSource="DocsList_NeedDataSource">

<MasterTableView AutoGenerateColumns="False">

<Columns>

<telerik:GridBoundColumn FooterText="Document" UniqueName="Document" SortExpression="ContactTitle"

HeaderText="Document" DataField="Document" Resizable="true">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn FooterText="Index" UniqueName="Index" HeaderText="Index"

DataField="Index" Display="false">

<ItemStyle Width="0px" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn FooterText="MediaURL" UniqueName="MediaURL" HeaderText="MediaURL"

DataField="MediaURL" Display="false">

<ItemStyle Width="0px" />

</telerik:GridBoundColumn>

<telerik:GridButtonColumn FooterText="View" ButtonType="ImageButton" UniqueName="View"

HeaderText="View" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center"

CommandName="Select" DataTextField="CustomerID" ImageUrl="~/Resources/Images/submit.png">

<ItemStyle Width="20px" />

</telerik:GridButtonColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

I have a few questions;

1. How can I attach an onclick event to the buttons in the button column so when a button in a row is clicked then value of one of the bound columns in the same row is returned?

2. The button images' seems to have an annoying shadow (image1.jpg attached). How can this be removed?

3. When this web page is being viewed in browser and browser window is scaled down the buttons start to crop instead of grid rescaling to allow the button to remain fully visible (image2.jpg attached). How can this be fixed?

Many Thanks

Regards

RadGrid doesn't fully support globalization (yet)

It looks like the usage of global resources isn't fully implemented yet in the latest version 2010.3.1317.40. For example the GridPagerItem still contains quite a few hardcoded texts. Furthermore I think it would be nice if the item commands would support globalization too. Is there any chance of an ETA for the completion of globalization support for RadGrid?

When the page is loaded the grid appears grouped, but if I remove the group draging it out from the group panel the grid is ungrouped and then I can't to group again draging a header or even reorder headers draging them.

<MasterTableView>

<telerik:GridGroupByExpression>

<GroupByFields>

<telerik:GridGroupByField FieldName="Usuario.Login" />

</GroupByFields>

<SelectFields>

<telerik:GridGroupByField FieldName="Usuario.Login" />

</SelectFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

</MasterTableView>

I have GroupingEnabled property set to true and also ShowGroupPanel. I was looking for a solution in the forum and I haven't found anybody with the same issue.
