Hello,
I have a template column which contains a lookup label. Label takes text from dictionary by ID contained in column. Column also has a templated filter which contains a combobox. When I select new item from dropdown, filter command fires and column must be filtered by combobox's ItemValue which is GUID. I  must say there is an extension method in my solution called ToGuid() which I use to convert string values. And now, when filtering command passes to server, I get the following error:

Sys.WebForms.PageRequestManagerServerErrorException: No applicable method 'ToGuid' exists in type 'Convert' (at index 9) в Telerik.Web.UI.ExpressionParser.ParseMemberAccess(Type type, Expression instance) в Telerik.Web.UI.ExpressionParser.ParseTypeAccess(Type type) в Telerik.Web.UI.ExpressionParser.ParseIdentifier() в Telerik.Web.UI.ExpressionParser.ParsePrimary() в Telerik.Web.UI.ExpressionParser.ParseUnary() в Telerik.Web.UI.ExpressionParser.ParseMultiplicative() в Telerik.Web.UI.ExpressionParser.ParseAdditive() в Telerik.Web.UI.ExpressionParser.ParseComparison() в Telerik.Web.UI.ExpressionParser.ParseLogicalAnd() в Telerik.Web.UI.ExpressionParser.ParseLogicalOr() в Telerik.Web.UI.ExpressionParser.ParseExpression() в Telerik.Web.UI.ExpressionParser.ParseParenExpression() в Telerik.Web.UI.ExpressionParser.ParsePrimary() в Telerik.Web.UI.ExpressionParser.ParseUnary() в Telerik.Web.UI.ExpressionParser.ParseMultiplicative() в Telerik.Web.UI.ExpressionParser.ParseAdditive() в Telerik.Web.UI.ExpressionParser.ParseComparison() в Telerik.Web.UI.ExpressionParser.ParseLogicalAnd() в Telerik.Web.UI.ExpressionParser.ParseLogicalOr() в Telerik.Web.UI.ExpressionParser.ParseExpression() в Telerik.Web.UI.ExpressionParser.Parse(Type resultType) в Telerik.Web.UI.GridDynamicQueryable.Where(IQueryable source, String predicate, Object[] values) в Telerik.Web.UI.GridDataTableFromEnumerable.FillData35() в Telerik.Web.UI.GridDataTableFromEnumerable.FillData() в Telerik.Web.UI.GridResolveEnumerable.EnsureInitialized() в Telerik.Web.UI.GridEnumerableFromDataView..ctor(GridTableView owner, DataView dataView, Boolean autoGenerateColumns, GridColumnCollection presentColumns, String[] additionalField, Boolean retrieveAllFields, Boolean enableSplitHeaderText) в Telerik.Web.UI.GridDataSourceHelper.CreateGridEnumerable(GridTableView owner, IEnumerable enumerable, Boolean caseSensitive, Boolean autoGenerateColumns, GridColumnCollection presentColumns, String[] additionalField, Boolean retrieveAllFields, Boolean enableSplitHeaderText) в Telerik.Web.UI.GridTableView.get_ResolvedDataSource() в Telerik.Web.UI.GridTableView.CreateChildControls(IEnumerable dataSource, Boolean useDataSource) в System.Web.UI.WebControls.CompositeDataBoundControl.PerformDataBinding(IEnumerable data) в System.Web.UI.WebControls.DataBoundControl.OnDataSourceViewSelectCallback(IEnumerable data) в Telerik.Web.UI.GridTableView.PerformSelect() в Telerik.Web.UI.GridTableView.DataBind() в Telerik.Web.UI.RadGrid.OnBubbleEvent(Object source, EventArgs e) в System.Web.UI.Control.RaiseBubbleEvent(Object source, EventArgs args) в Telerik.Web.UI.GridItem.OnBubbleEvent(Object source, EventArgs e) в System.Web.UI.Control.RaiseBubbleEvent(Object source, EventArgs args) в Telerik.Web.UI.GridItem.OnBubbleEvent(Object source, EventArgs e) в Telerik.Web.UI.RadGrid.RaisePostBackEvent(String eventArgument) в System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

I'm not sure whether this is an error in your code or mine or whatever else. Can you please check this out?
Thank you.

I've added an ASP.NET required validator on a Telerik textbox.  I've noticed that the validator reports the contents of the textbox to be empty when the screen is first rendered, even though the textbox was prepopulated with text from a database.  Refreshing the screen seems to make the validator recognize the text again.

I know telerik textboxes render as three input controls.  Could the validator be trying to read the wrong input control?

Hello,

Can I create the following table?

 

 

A	B	C
		D	E			I
			F	G	H

 
I would like to merge some of the columns.

Can you show me a sample code?


Thank you for your help.

I'm using the keyboard controls for the RadGrid, however, when i hit enter on a line to edit it, i need it to go to a column that i specify.

The RadGrid has AutoGenerated Columns, and editting is in place.

I've been looking through the forums & KB for the resolution and i see demos and answers if you use an edit form.

I tried to use the following code to set the focus, but the focus isn't really set on the text box, and causes a javascript error when you stop editting.

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
        {
            if (e.Item.IsInEditMode)
            {
                string script = String.Format("$get('{0}').focus(); $get('{0}').select();", ((TextBox)e.Item.FindControl("ctl01")).ClientID);
                ScriptManager.RegisterStartupScript(Page, typeof(Page), "myscript", script, true);
            }
        }

Hi,

i'm adding validator through the ItemCreated for the datetime column. The grid is giving me
Unable to cast object of type 'System.Web.UI.WebControls.Panel' to type 'System.Web.UI.WebControls.TableCell'.

the following is my c# code.

 

 

GridDateTimeColumnEditor editorStartTime = (GridDateTimeColumnEditor)item.EditManager.GetColumnEditor("StartRunTimeColumn");

 

cell = (

 

TableCell)editorStartTime.SharedTimeView.Parent;

 

RequiredFieldValidator

 

 

Validator =

 

new RequiredFieldValidator();

 

editorStartTime.SharedTimeView.ID =

 

"StartRunTimeColumn";

 

Validator.ControlToValidate = editorStartTime.TextBoxControl.ID;

Validator.BackColor = System.Drawing.

 

Color.Red;

 

Validator.ErrorMessage =

 

"*";

 

cell.Controls.Add(Validator);

 

 

hi all,

<telerik:RadGrid ID="grid1" runat="server" GridLines="Both" HeaderStyle-Width="100px"

 

 

 

Width="500px" OnItemDataBound="grid1_ItemDataBound" CssClass="rgTwoLines"

 

 

 

Skin="Outlook" ItemStyle-HorizontalAlign="Left" AlternatingItemStyle-HorizontalAlign="Left"

 

 

 

MasterTableView-TableLayout="Fixed" Style="overflow: auto" >

 

 

 

<ClientSettings>

 

 

 

<Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="true" FrozenColumnsCount="1">

 

 

 

</Scrolling>

 

 

 

</ClientSettings>

 

 

 

</telerik:RadGrid>

Above is my code. i am using this to freeze column and also for static header. one of the problem is that, even though grid has one row the height has still same and shows with unneccessary white space in height.
But if many rows then it is working fine as what i expected. Please see image for reference.
Any solution for this?

 

Hi,

We have just purchased the RadControls for ASP.Net/Ajax, and I am working in .Net 3.5.

I have a radmenu nested in a splitter that's working fine in IE, but the dropdowns are not overlaying in Chrome.

I've also noticed that the float: right doesn't seem to be rendering properly in chrome.  I'd actually like the logout and skin chooser menu items to be aligned to the right, but I'm having issues with that too.  I have tried palying with the z-index but that doesn't seem to help.

Any help would be greatly appreciated.  Thanks!

Hi!
I've written some code that will enable/disable buttons and context menu options based on certain conditions on the folders. I started out with the sample found here http://www.telerik.com/community/forums/aspnet-ajax/file-explorer/prevent-delete-of-top-folder.aspx but have refactored out the event hookups to javascript like this: (instead of hooking them in the aspx markup of the File Explorer control)


The problem I have is that after any kind of moving files and folders through drag and drop operations in the file explorer the ContextMenuShown event doesn't trigger any more so all options are available in the menu for all folders. The events for the File Explorer still works though.

Any help on this is appreciated.

I have a C#.NET page setup with a left and right RadPane. The left pane contains several radgrids situated in a RadPanelBar. (similar to an Outlook layout). In the RadPanelBar i have three RadPanelItems: one RadPanelItem contains a customer RadGrid, the second contains a customer Query Builder Form with three buttons and the third RadPanelItem contains two Grids. Those two grids contain info about saved queries and any lookup results, respectively. Here are the grid names for easy reference going forward (code will be provided below).

customerGrid, existingQueryGrid, custQueryResultsGrid

I have a RadToolTipManger assigned to customerGrid on ItemDatabound to display customer info on mouseover. I also have a separate RadToolTipManager for existingQueryGrid (also assigned target controls on databound) so the user can mouseover the saved lookup by name and view the lookup filter details.

I also have two user controls setup in the right side RadPane which contain radgrids with their own RadToolTipManager connections working in a similar way.

Scenario 1) When one submits a lookup from the query form, it populates existingQueryGrid (tooltips are bound on page load) and/or the custQueryResultsGrid depending on the query request ("save", "save and lookup" or just "lookup").Upon completion of the AJAX, any grids that were not Rebound no longer have the RadToolTips working. For example if one hits the "save" command then only the existingQueryGrid  is updated (since they only wanted to save the query) and therefore ToolTips are recreated and include a new record (works fine); however, since the customerGrid was not rebound here, the ToolTip for that Target Control set is no longer working.

Scenario 2) When one clicks a record from customerGrid, it loads the contact information into the user controls in the right pane and all the ToolTips are initialized and working when the respective user control Radgrids for Accounting and Product info are first bound. At this point the ToolTIp on the customerGrid is no longer functioning, and if  any other type of command is performed on customerGrid  like paging or filtering, the user control RadGrid ToolTips for the Accounting and Product  are no longer functiong until they are paged or sorted (at which point it works again).

All RadGrids and their respective tooltips are placed in the RadAjaxManager (and RadAjaxManager Proxy for user controls) settings so when one updates, the tooltip also should update. I am providing some relevant code:

MAIN PAGE (CLIENT SIDE)


MAIN PAGE (SERVER SIDE for customerGrid)


MAIN PAGE (SERVER SIDE for existingQueryGrid)

 
Let me know if you need more information or code. The above code pertains to Scenario 1 but I believe once we solve (1),
we will solve (2).

Thanks in advance

I'm having an issue with style and formatting specifically with the docks - under localhost the style and formatting works as expected.  When I use my machine name to access the site under development the formatting goes out the door.

I've removed all css file references and put the style within the page and put inline style attributes to try and force the format.

Anything off the top of your head that might come to mind?

TIA,
-vic
