Hi Everyone,

I needed help to solve the problem:
    My ISSUE is I had a Rad grid in which the columns are automatically generated
The grid code looks like this

<telerik:RadGrid ID="rgTSSearch" runat="server" Skin="Outlook" Width="97%" ShowStatusBar="True"
        AllowSorting="True" PageSize="10" GridLines="None" OnColumnCreated="rgTSSearch_ColumnCreated"
        OnItemCreated="rgTSSearch_ItemCreated" OnNeedDataSource="rgTSSearch_NeedDataSource"
        OnItemCommand="rgTSSearch_ItemCommand" OnUpdateCommand="rgTSSearch_UpdateCommand"
        OnCancelCommand="rgTSSearch_CancelCommand" OnInsertCommand="rgTSSearch_InsertCommand">
        <PagerStyle Mode="NextPrevAndNumeric" />
        <MasterTableView Width="100%" DataKeyNames="ID" CommandItemSettings-ShowAddNewRecordButton="false"  CommandItemDisplay="Top" HorizontalAlign="NotSet">
            <CommandItemTemplate>
                <asp:LinkButton ID="btnInitInsert" runat="server" CommandName="InitInsert"><img style="border:0px;vertical-align:middle;height:20px; width:20px;" alt="" src="../../App_Themes/add.png" />Add new TS</asp:LinkButton>
                &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
                <asp:LinkButton ID="btnRebind" runat="server" CommandName="RebindGrid"><img style="border:0px;vertical-align:middle; height:20px; width:20px;" alt="" src="../../App_Themes/refresh.png" />Refresh</asp:LinkButton>
            </CommandItemTemplate>
            <Columns>
                <telerik:GridEditCommandColumn ButtonType="ImageButton" HeaderStyle-Width="10%" UniqueName="EditColumn" />
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>

In the automatic generated columns there are two bit datatype columns which are generated as a checkbox column.

Now when I edit a particular row how to set the check box in the edit form[External form] based on the value in the grid
I mean If the check box column in the grid is checked then the checkbox column in the External form should be checked .

I tried in different ways but nothing worked out .


So please help me......


Thanks In advance,

Hi Guys,

is there any reason why datatable visible on attached screenshot is displayed like this (see attached)?

DataGroupColumn property is set to "Days" and DataLabelsColumn (PlotArea.XAxis.DataLabelsColumn) to "TaskName"... The data is correct but it is displayed under wrong labels.

I checked examples in the documentation and can't see any differences between my way of populating the chart and yours.

Cheers,
Kamil

Hi,

I would like to reduce the RadFilter filter menu items based on editor type. I have read some forum posts like:
http://www.telerik.com/community/forums/aspnet-ajax/filter/custom-list-of-filter-functions-for-custom-field-editor.aspx
to limit filter menu items based on datatype and field name but I would like to do same thing based on editor type especially RadFilterDropDownEditor. I would like to show only Equal, NotEqual options if the added editor is RadFilterDropDownEditor.

Thanks in advance.

Hi,
I am trying to add several custom buttons, but still have the problems with calling the editor.fire function. It works perfectly for some primitive functions like Bold, JustifyLeft etc. and it's well documented. But I spent a lot of time searching the proper syntax for setting the ForeColor property (the result was 

Telerik.Web.UI.Editor.CommandList[

"Blue"] = function(commandName, editor, args) { editor.fire("ForeColor", { value: "#2e2e6c" }); };

 

Now I am in the same position when trying to fire the FlashManager dialog. While Telerik.Web.UI.Editor.CommandList["InsertPicture"] = function(commandName, editor, args) { editor.fire("ImageManager"); }; works well, the similar Telerik.Web.UI.Editor.CommandList["InsertFlash"] = function(commandName, editor, args) { editor.fire("FlashManager"); }; shows the error message "Dialog parameters for the FlashDialog doesn't exist". Could you tell me the proper syntax?

And another question. Is it possible to hide the "EditModes" buttons at the bottom line (e.g. via css .rade_editorModesCell {display: none !important;}) and invoke the change of the EditMode by clicking my custom buttons (similar to calling javascript editor.fire function)?

I would like to have a GridButtonColumn that begins an Insert in the DetailsTable under the current row.  Is this possible?  Basically, I can do an insert in the DetailsTable by showing the command row, but that row doesn't fit well in my grid and I would like to have the Add button show up in the parent row instead.  I have a button and can catch the ItemCommand from the main grid, but can I initiate the Insert in the details table from there?

Hi
I've used RadInputManager to manage my input controls validating
Because I'm using User Controls , I need to set the ValidationGroups in code to a uniqe name that are based on the User Contro ID , to have the ability to use more than one of the same User Control in a page.
By a code like this :

           RadInputManager1.InputSettings[0].Validation.ValidationGroup = "xxcc"

I placed this line in Page_Load , Page_Init and even in InputSettingCreating event handler (by using the specila event argument)
But it seems that it's not working properly
Please help me , what's my problem ?
Thanks for your feedbacks.
