[Solved] How to ReSize column of PivotGrid

Hi,

In RadGrid, If we want the columns in our grid to be resizable, set the ClientSettings.Resizing.AllowColumnResize property to True.

Is there any way or property in RadPivotGrid so we can resize our column and row of Pivotgrid?

Is Pivotgrid support column resize on client same as RadGrid support?

Thanks.

RadGrid - Paging Doesn't Work When Building Grid Dynamically

Hi,
I'm new to Telerik. Virtually all of the pages I work with are actually user controls, being built entirely dynamically, usually in OnInit. I'm finding it hard to get the Grid (first control I've tried) to behave in this situation. Any client actions performed don't seem to produce the intended result. For instance, Paging just stays on Page 1, Page Size does not take, etc.

You'll notice I'm using the Ajax Panel, but I've tried it without, as well. Thought it might have to do with ViewState/Postback and you can see commented code related to this, but all the permutations I've tried produce the same behavior.

Most of this code was copied and pasted from Telerik demos, primarily the sample at http://www.telerik.com/help/aspnet-ajax/grid-programmatic-creation.html#Section3.

Thanks in advance for your feedback.

Jscript error on Legend mouseover for HtmlChart with mixed Series

Hi there,

I'm using Telerik RadControls for ASP.NET version v.2013.2.717.45 on Internet Explorer 8 using Visual Studio 2012.

I've been working on a RadHtmlChart that has 3 Column Series (stacked) and 1 Line Series. The Chart is databound and the data representation, as well as everything else, is working just fine for the chart. The only issue I have now is that when I added the Line Series to the Chart (thereby making the Chart a mixed series chart), there is a Jscript error when a user mouses over the Legend. The error is:

'options' is null or not an object

As soon as I remove the Line Series, the error goes away.

Any advice would be greatly appreciated!

Here is my RadHtmlChart:

Multiple controls with the same ID were found. FindControl requires that controls have unique IDs

Hi all,

I'm hoping someone out there may be able to help with this issue I'm having.

Scenario:
I have a page containing a radsplitter which is divided into 3 main panes: Across the top, down the left-hand side and the third is the main content panel.

Within the left-hand pane I have nested splitters and a panelbar, using templated panels that contain ajaxified radgrids (using advanced binding). In the main content pane I have a tabstrip and multipage.

No controls are being added dynamically/programmatically, other than tabs being added using client-side scripts from within the main content pane.

Now the problem:
If I do not open any tabs everything works great - the grids page nicely and everyone is happy.
If, however, I open a tab, after 3-4 paging operations on the grids I get the dreaded Multiple controls with the same ID were found. FindControl requires that controls have unique IDs.

Now I *know* there are no controls being added between the ajax paging postbacks. And the error only occurs after 3-4 actions taking place on the grid as opposed to immediately. Disabling ajax I still continue to get the error.
I have no RadAjaxPanels anywhere - everything is hooked up using the RadAjaxManager.
If I remove the grid outside of all the radsplitter/panelbar elements the problem persists.
I have gone through all my code and made absolutely certain that every control has a unique ID (radcodeblocks, pageviews etc).
There are no pageLoad() or document.ready functions being used.

I'm completely stumped. the stack trace shows that the problem occurs after the tabstrip PreRender process:

[HttpException (0x80004005): Multiple controls with the same ID 'ctl01' were found. FindControl requires that controls have unique IDs.]

System.Web.UI.Control.FillNamedControlsTable(Control namingContainer, ControlCollection controls) +12651760

System.Web.UI.Control.FillNamedControlsTable(Control namingContainer, ControlCollection controls) +317

System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +320

Telerik.Web.UI.RadTabStrip.OnPreRender(EventArgs e) +103

I've reviewed this post http://www.telerik.com/help/aspnet-ajax/ajax-content-type.html but it's not applicable because I'm not dyanmically adding controls. I've also tried the javscript from this post http://www.telerik.com/help/aspnet-ajax/tabstrip-faq.html but still the problem persists.

Can anyone offer any suggestions about where I should should look next?

Help!

Attaching Context Menu to RadGrid Row

I want to attach a context menu to each radgrid row runtime, as each row may have a different context menu. I don't want to hard code the menu items in the context menu.

I am having a hard time figuring out how to do this.

Here is the code.

Dim rmi3 As New RadMenuItem()

Dim rcm3 As New RadContextMenu()

Dim editZone As ContextMenuControlTarget = New Telerik.Web.UI.ContextMenuControlTarget()

rmi3.Text = "Preparer"

rmi3.Value = "1"

rcm3.ID = "Role" & i

rcm3.Items.Add(rmi3)

Dim rmi4 As New RadMenuItem()

rmi4.Text = "Reviewer"

rmi4.Value = "2"

rcm3.ID = "Role" & i

rcm3.Items.Add(rmi4)

Dim rmi5 As New RadMenuItem()

rmi5.Text = "View PDF"

rmi5.Value = "3"

rcm3.ID = "Role" & i

rcm3.Items.Add(rmi5)

editZone.ControlID = row.dataitem("usqnumber")

rcm3.Targets.Add(editZone)

Me.Controls.Add(rcm3)

Save to Azure

Hello,

I've uploaded files to Azure blobs using Telerik controls with the AsyncUpload control. The UploadedFile.InputStream works great with Azure's blob upload.

Is there a similar way to access the image stored in the ImageEditor control? My current idea is to save the file to the local VM and then use that stream to upload the blob.

Edit: Issue now is that the image is being saved from the ImageEditor control but it is not the edited image it is just the original - I think because I'm using a server side call.

I am using the most current version of Telerik ASP.NET controls on the most recent version of Chrome for Windows but would want the solution to work across all modern browsers (Chrome, FF, IE9+).

Thank you,

Shaw

OnPageIndexChanging event in RadGrid

Hi Team,

We have a scenario where the entire grid will be editable and the grid will have pagination.

What we are trying to achieve is - Let say user made changes to data on a page 1 and then if user clicks on any other page, we want to show a confirmation dialogue "Do you want to save the changes made..." with Yes - No - Cancel button.
If user selects 'Yes' then data will be saved and navigate to selected page
If user selects 'No' then data will not be saved and navigate to selected page
If user selects 'Cancel' then grid will remain on same page with all the edited data.

I assume if we have OnPageIndexChanging event in RadGrid then it could have been achived, but RadGrid only have OnPageIndexChanged event.

Kindly help on this. We are using Q3, 2011 version.

Regards
Tripati Patro
