Hi Telerik,

I'm having an issue with the RadGrid control.

After resizing my browserwindow my radgrid is being resized.
It changes my height with a few pixels.

I tried debugging the javascript and in the setDataDivHeight function it decides to  remove 17 pixels because Telerik.Web.UI.Grid.getScrollBarHeight() returns 17. But I didn't have a scrollbar!

Currently i'm using Telerik controls version: 2011.2.915.35.

Is there a workaround for this?

Is it possible to change this from the dashed default?  I assume it is just a style, but I cannot locate it.

Thanks,

Steve

Hello,

I currently have RadGrids that I am creating dynamically in Page Load that are embedded in PanelBar Items.  The grids create fine and render on the page.  They have the initial appearance of drag and drop, but when the row is released into the new grid, the routine tied to the RowDrop event (GridRowDrop) does not fire and the Page appears to do a PostBack.  I believe this has to do with something with AJAX settings, but not certain.

Here is a snippet from the code-behind:


Any help is appreciated.

Hi there,

Am using RadTagCloud.
I have user control on this page with RadTagCloud,  this user control using in my aspx page.
but ItemClick event is giving problem like Object reference not found.

Below find my code snnipet
code behind if UserControl 
public partial class ucCustomerSelector : System.Web.UI.UserControl
  {
    public EventHandler rtcLinksClicks;


    protected void Page_Load(object sender, EventArgs e)
    {
    }


    protected void rtcLinks_ItemClick(object sender, Telerik.Web.UI.RadTagCloudEventArgs e)
    {
      rtcLinksClicks(sender, e);
    }


  }
******************************************
code behind of aspx page
public partial class CustomerPage : System.Web.UI.Page
  {
    


    protected void Page_Load(object sender, EventArgs e)
    {
      
      if (!Page.IsPostBack)
      {
        
        ucCustomerSelector.rtcLinksClicks += new EventHandler(myclick);
      }
    }


    private void myclick(object sender, EventArgs e)
    {
      // my logic wil come here.
    
    }
}
please give me solution, I am waiting for reply.
thanks in advance.

In the popup that opens when I insert or edit one item in the grid, some logic has to be done, for example: enable and disable fields, depending on the values of other fields.

How can I add an onload event for the popup so that I can run js code to perform those enable/disable?

I already tried the OnPopUpShowing event, but it doesn’t work with date pickers, it fails in the get_selectedDate() because the _dateInput is empty (return this._dateInput.get_selectedDate())

Here’s the grid and javascript (simplified):

<RadGrid runat="server" ID="Grid1" AllowPaging="True" GridLines="None" CellSpacing="0" Culture="English (United Kingdom)" AllowSorting="True" AutoGenerateDeleteColumn="True" Width="95%" AllowAutomaticDeletes="True" AllowAutomaticInserts="True" AllowAutomaticUpdates="True" DataSourceID="ControlPanelNotifications_DS">

<MasterTableView DataKeyNames="fldId" DataSourceID="ControlPanelNotifications_DS" EditMode="PopUp" AutoGenerateColumns="False">

<CommandItemSettings ExportToPdfText="Export to PDF"></CommandItemSettings>

<RowIndicatorColumn Visible="True" FilterControlAltText="Filter RowIndicator column"></RowIndicatorColumn>

<ExpandCollapseColumn Visible="True" FilterControlAltText="Filter ExpandColumn column"></ExpandCollapseColumn>

<Columns>

…

<ItemStyle HorizontalAlign="Center" Width="40px"></ItemStyle>

</sqr:GridButtonColumn>

</Columns>

<EditFormSettings CaptionFormatString="Detalhes" EditFormType="Template">

<EditColumn FilterControlAltText="Filter EditCommandColumn column"></EditColumn>

<FormTemplate>

<table style="width: 100%;">

<tr>

    <td>

                label

    <td>

                text

    <td>

                Label2

    <td>

                <RadDatePicker runat="server" ID="dtPracticalDate" Width="100px">

          <ClientEvents OnDateSelected="dtPracticalDate_DateSelected" />

        </RadDatePicker >

                <BindableControl runat="server" DataField="PraticalDate" TargetControlID="dtPracticalDate"></BindableControl>&nbsp;</td>

</tr>

<tr>

    <td>

                Label3

    <td>

    <td>

                <RadDatePicker runat="server" ID="dtConfirmationDate" Width="100px">

          <ClientEvents OnDateSelected="dtConfirmationDate_DateSelected" />

        </RadDatePicker >

                <BindableControl runat="server" DataField="ConfirmationDate" TargetControlID="dtConfirmationDate"></BindableControl>&nbsp;</td>

</tr>

</table>

 

<asp:Button runat="server" CommandName="Cancel" Text="Cancelar"></asp:Button>

 

</FormTemplate>

<PopUpSettings Modal="True" Width="570px"></PopUpSettings>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False"></FilterMenu>

<ClientSettings>

<ClientEvents OnPopUpShowing="PopUpShowing"></ClientEvents>

</ClientSettings>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default"></HeaderContextMenu>

</RadGrid>

Javascript:

function PopUpShowing(sender, eventArgs) {

    var practicalDate = getElementById('dtPracticalDate').get_selectedDate();

    UpdateConfirmationDate22(practicalDate);

}

function UpdateConfirmationDate22(practicalDate) {

    var confirmationDatePicker = getElementById('dtConfirmationDate');

    if (practicalDate != null) {

        confirmationDatePicker.set_enabled(true);

    }

    else {

        confirmationDatePicker.set_enabled(false);

        confirmationDatePicker.clear();

    }

}

Hi ,


I would like to know what is the difference between the Telerik.WebControls.RadEditor and the Telerik.Web.UI.RadEditor ?

if I will need to change the existing code to use the Telerik.Web.UI.RadEditor instead of the Telerik.WebControls.RadEditor
 how and where can i find the corresponding property of the Telerik.WebControls.RadEditor with the Telerik.Web.UI.RadEditor ?

for example :  Telerik.WebControls.RadEditor.Editable,  DialogParametersMode,  HasPermission etc.

Any sample or documentation will be greatly appreciated


Thanks In Advance

Hello, 

I'm using Telerik's RadAjaxManager to update panels independently.

On my page, I have 3 user controls: A, B, C.

My AjaxSettings are:

• If postback on A, update only A.
• If postback on B, update only B.
• I declare nothing for C.

If I do a postback on A, I see the loading panel on A, but (using Chrome dev tool) I see data sent for A and B. Strange to me as only A has loading panel.

If I do as postback on B, same behavior: loading panel on B but data for A and B.

Now, if I remove from AjaxSettings the settings for B, when I do a postback on A, only data for A are sent.

Am I wrong, or I should only see data for the "target" panel defined in AjaxSettings?

Moreover, sometimes in our user controls we access the RadAjaxManager to add response script. Can it be related? For instance, if in B's code-behind I add script to RadAjaxManager, will the entire B content will be sent when I do a postback on A (with rule A updates A only)?

This is really an issue in our app.

Thanks in advance for any help.

Hi there, I have come across a problem with the Rad Grid shrinking in size when it's rebound, or when it's item command it hit.

I will explain where my grid sits, It is in a control which is situated in a RadWindow which contains a tab strip it is one of the page contols of one of the rad tabs.

The RadGrid is set up with the following code:


    <telerik:RadGrid ID="RadGrid1" runat="server" AllowSorting="true" AllowPaging="true" AutoGenerateColumns="true" OnNeedDataSource="RadGrid1_NeedDataSource"
        OnColumnCreated="RadGrid1_ColumnCreated" OnItemDataBound="RadGrid1_ItemDataBound" AllowMultiRowSelection="true" ShowGroupPanel="true" OnItemCommand="RadGrid1_ItemCommand">
        <MasterTableView TableLayout="Fixed" Width="100%">     
            <Columns>
                <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn">
                    <HeaderStyle Width="50px" />
                </telerik:GridClientSelectColumn>
                <telerik:GridButtonColumn DataTextFormatString="Download" UniqueName="DownloadLink" CommandName="Download"
                        runat="server" DataTextField="ID" ButtonType="LinkButton" >                    
                </telerik:GridButtonColumn>                                     
            </Columns>                        
        </MasterTableView>
        <ClientSettings EnableRowHoverStyle="true" AllowDragToGroup="true" AllowColumnsReorder="true">
            <Selecting AllowRowSelect="True" UseClientSelectColumnOnly="true" />      
            <Resizing AllowColumnResize="True" AllowRowResize="false" ResizeGridOnColumnResize="false"
              ClipCellContentOnResize="false" EnableRealTimeResize="false" AllowResizeToFit="false" />                   
        </ClientSettings> 
    </telerik:RadGrid> 

When the page first loads the grid renders as desired, however once it has been updated or the Download command has been run the grid shrinks all columns so that the contents of the cells are spread over 3 lines.

Any ideas on how to stop this from happening?

Ryan
