Issue with the drop down element position of RadComboBox inside RadWindow.

Hi,

I have come across a strange behavior with the RadWindow control. I added a RadComboBox in the ContentTemplate of a RadWindow. On clicking the RadComboBox the drop down opens and if I click the Close button of the RadWindow without selecting any item, the RadWindow gets closed but the drop down element is still visible to the user and items can be selected.

Another issue is I open the RadWindow and click the Maximize button in the title bar and the RadWindow gets maximized. Now when the RadComboBox is clicked, the drop down element is not visible to the user. Once the maximized window is closed (even Minimized), the drop down element can be seen in the corresponding position in the screen where the RadComboBox is rendered inside the RadWindow. The user is able to select any item from the drop down element. This issue can be replicated with any RadControl(any version) that has a drop down element such as RadDropDownList, RadDropDownTree.

Here is the code I tried.

ASPX:

<telerik:RadWindow ID="RadWindow1" runat="server" OpenerElementID="RadButton1">

<ContentTemplate>

<br />

<telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged">

<Items>

<telerik:RadComboBoxItem runat="server" Text="Item A" />

<telerik:RadComboBoxItem runat="server" Text="Item B" />

<telerik:RadComboBoxItem runat="server" Text="Item C" />

</Items>

</telerik:RadComboBox>

</ContentTemplate>

</telerik:RadWindow>

<telerik:RadButton ID="RadButton1" runat="server" Text="Open RadWindow">

</telerik:RadButton>

JavaScript:

<script type="text/javascript">

function OnClientSelectedIndexChanged(sender, args) {

alert("OnClientSelectedIndexChanged Fired");

}

</script>

I took a sample video of this strange behavior and you can find it here.

Thanks,
Shinu.

Change ItemTemplate binding code behind

Hello,

I would like to change the binding of the ItemTemplate of a GridTemplateColumn in code behind. I am trying to use the click event of a button outside of the grid to change the binding. On the button click, I would like change the Text value of the ItemTemplate to '<%#Eval("Choose")%>'. Please assist.

APSX:

<telerik:GridTemplateColumn HeaderText="SSA Decision" SortExpression="SSA_Decision" UniqueName="SSA_Decision">

<ItemTemplate>

<asp:Label ID="lblSSADecision" runat="server" Text='<%#Eval("SSA_Decision")%>' />

</ItemTemplate>

<EditItemTemplate>

<telerik:RadComboBox runat="server" ID="cboSSADecision" Skin="WebBlue" Width="105px">

<Items>

<telerik:RadComboBoxItem Text="Yes" Value="True" />

<telerik:RadComboBoxItem Text="No" Value="False" />

<telerik:RadComboBoxItem Text="Please Choose" Value="Choose" Selected="true" />

</Items>

</telerik:RadComboBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

Thanks!

Command bar

Has there been a change to the height of the command bar for the grid with the Material theme? I did a test install and one of the issues that I have with it is that the command bar height seems to be the same as any content. Before there was some padding or a margin to force some extra height to it. I'm interested to hear if this is a bug or if there has been a change to the skin.

Regards

Jon

Material Skin font size issues

Please see this page to demo some size issues. Something in the popup form is causing the font size to increase. Make sure skin is set to Material.

http://demos.telerik.com/aspnet-ajax/spell/examples/overview/defaultcs.aspx

Interestingly the buttons are set to inherit the font size, not sure why but the css inspection doesn't reveal what the source of the increased size is.

Drag and Drop with RadProgressArea

Hi,

I have a project which allows upload of large files using drag and drop functionality and saves it to the file system. I use RadProgressArea to show the upload progress for these large files. When I drag and drop a huge video file in the drop zone, the radprogressarea starts displaying the progress, while the file is still uploading I drag another file to the drop zone. The RadProgressArea hangs and loses the first file which was uploading. It works good without any issue when I chose multiple large files and drag and drop in the drop zone at the same time.Can anyone let me know what I am missing?

(I am using Telerik for asp.Net version 2016.1.225.45)

Thanks

Migrating from Telerik.WebControls.RadGrid (RadGrid.Net2.dll) to Telerik.Web.UI.RadGrid (Telerik.Web.UI.dll Q2 2016)

I'm currently going through updating an application that was using RadGrid.Net2 and RadChart.Net2, to be using the latest release of Telerik ASP.NET AJAX Grid and Chart controls.

So far I've encountered numerous issues with skinning of the Grid, and am now experiencing issues with some of the databinding and controls usage for the grid which I'm hoping you could advise on.

One of the failing instances of the RadGrid used to use the following code:-

<radG:RadGrid id="GridOutcomes" runat="server" AllowSorting="True" AllowPaging="True" AutoGenerateColumns="False" GridLines="None" Skin="Default" OnNeedDataSource="GridOutcomes_NeedDataSource" OnItemCommand="GridOutcomes_ItemCommand" OnItemDataBound="GridOutcomes_ItemDataBound" Visible="False">

<MasterTableView DataSourcePersistenceMode="NoPersistence">

<Columns>

<radG:GridBoundColumn DataField="ID" HeaderText="Case" UniqueName="columnId" Visible="False" /> <radG:GridTemplateColumn DataField="GmcCode" HeaderText="GMC" UniqueName="columnGMC" SortExpression="GmcCode"> <ItemStyle HorizontalAlign="Left" />

<HeaderStyle HorizontalAlign="Left" />

<ItemTemplate>

<des:Button ID="ButtonDrillDown" runat="server" CssClass="linkButtonNoValidate showInPrint" CommandName="DrillDown" Text='<%#((string)Eval("GmcCode")) + " "%>' CausesValidation="false" />

</ItemTemplate>

</radG:GridTemplateColumn>

<radG:GridBoundColumn DataField="FormattedName" HeaderText="Name" UniqueName="columnName" />

</MasterTableView>

<PagerStyle Mode="NextPrevAndNumeric" />

</radG:RadGrid>

With the Telerik DLLs updated, I've noticed that the 'DataSourcePersistenceMode' property is no longer valid for the MasterTableView.

Also, when the application runs, clicking on one of the row buttons which calls 'GridOutcomes_ItemCommand' no longer is able to extract the correct value from the grid, and the value returned is the Empty Cell Default Value.

01.protected void GridOutcomes_ItemCommand(object source, GridCommandEventArgs e)

02.{

03. Logger.Write(User.Identity.Name + ": SearchPersonnel:GridOutcomes_ItemCommand", Defines.LoggingCategoryMain);

04.

05. switch(e.CommandName)

06. {

07. case "DrillDown":

08. try

09. {

10. GridDataItem gridItem = e.Item as GridDataItem;

11. TableCell cell = gridItem[GridOutcomes.Columns[(int)GridColumn.PersonnelId].UniqueName];

12.

13. int personnelId = 0;

14. if(int.TryParse(cell.Text, out personnelId))

15. {

16. ApplicationStore.Instance.SelectedPersonnel = new Personnel(new PersonnelRecord(), personnelId);

Could you please advise on what I should do to replace the missing DataSourcePersistenceMode property in order to retain the same functionality, and also could you please let me know if you have a guide on migrating from the .Net2 versions of the RadGrid and RadChart to the up to date releases since I'm guessing I'm going to find a lot of issues when I get to testing the chart control.

Thanks,

Jonathan
