Chart populated by DataTable

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

Reduce the RadFilter filter menu items based on editor type.

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.

editor.fire command

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)?

DetailTable insert from parent table?

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?

protected void g1_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == "AddPI")

{

// What goes here to init insert in detailstable[0]?

//e.Item.OwnerTableView.DetailTables[0].???

}

RadInputManager ValidationGroup changing by code doesn't work

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.

Column 'xyz' does not belong to table DefaultView.

Hi all,

I have a RadGrid with has a custom template for inserting records. Once I insert the record, I try to close the insert template with the following code:

else if (e.CommandName == RadGrid.PerformInsertCommandName)

{

e.Canceled = true;

e.Item.OwnerTableView.InsertItem();

RadGrid_Visitor_RT.MasterTableView.IsItemInserted = false;

RadGrid_Visitor_RT.Rebind();

}

Calling the Rebind() method throws the following error:

Column 'Function_Key_Description' does not belong to table DefaultView.

The code for the RadGrid is below.

<telerik:RadGrid ID="RadGrid_Visitor_RT" runat="server" AutoGenerateColumns="false" Width="100%"

AllowMultiRowSelection="false" AllowPaging="True" AllowCustomPaging="False" PageSize="10" AllowAutomaticInserts="False"

GridLines="None" CellPadding="0" AllowSorting="false" Skin="Outlook" OnItemDataBound="Visitor_RT_ItemDataBound"

ItemStyle-VerticalAlign="Top" OnNeedDataSource="RadGrid_Visitor_RT_NeedDataSource"

OnItemCommand="RadGrid_Visitor_RT_ItemCommand">

<PagerStyle Mode="NextPrevAndNumeric"/>

<MasterTableView Width="100%" CommandItemDisplay="Top" GridLines="None" AllowAutomaticInserts="True">

<CommandItemSettings ShowAddNewRecordButton="true" AddNewRecordText="Create Transaction" ShowRefreshButton="false" ShowExportToCsvButton="false"

<telerik:GridImageColumn DataType="System.String" AlternateText="F_Key"

DataAlternateTextField="Function_Key_Description" UniqueName="GridImageColumn_Function_Key"

ImageAlign="Middle" ImageHeight="16px" ImageWidth="23px" HeaderText=""

DataImageUrlFields="Function_Key_Description"

DataImageUrlFormatString="Images/OnTime_Fkeys/{0}.png" HeaderStyle-Width="10%"/>

<telerik:GridBoundColumn UniqueName="Terminal_Name" DataField="Terminal_Name"

HeaderText="Terminal Name" HeaderStyle-Width="25%" Visible="true" ItemStyle-VerticalAlign="Top"/>

<telerik:GridBoundColumn UniqueName="Terminal_Location" DataField="Terminal_Location"

HeaderText="Terminal Location" HeaderStyle-Width="30%" Visible="true" ItemStyle-VerticalAlign="Top"/>

</Columns>

Can anyone tell me why the Rebind method is throwing this error on the GridImageColumn?

Thanks,

Sunny

Following code retrieve the PK value:

GridDataItem item = (GridDataItem)e.Item;

int ControlId = Convert.ToInt32(item.OwnerTableView.DataKeyValues[item.ItemIndex]["ControlID"]);

RadGrid template:

<

telerik:RadGrid ID="radCntDets" runat="server" GridLines="None" Width="938px"

AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False"

OnNeedDataSource="radCntDets_OnNeedDataSource"

Codebehind:

GridEditableItem

editedItem = e.Item as GridEditableItem ;

GridEditManager editMan = editedItem.EditManager;

string _cType = string.Empty;
foreach (GridColumn column in e.Item.OwnerTableView.RenderColumns)

{

if (column is IGridEditableColumn)

{

IGridEditableColumn editableCol = (column as IGridEditableColumn );

if (editableCol.IsEditable)

{

IGridColumnEditor

editor = editMan.GetColumnEditor(editableCol); -----> Error:Specified argument was out of the range of valid values.

if (editor is GridTemplateColumnEditor)

{

if (column.UniqueName.Equals("ControlType" ))

_cType = ((

TextBox)(((Telerik.Web.UI.GridColumnEditorBase)((editor as GridTemplateColumnEditor

))).ContainerControl).Controls[1]).Text;

}

}

Please advise me how to access the value of a template controlType in bold.

Thanks
Indra
