Binding combobox to SQLDS in radGrid inplace edit template.

I've bound data to a radgrid which I'm using to just reimplement a preexisting gridview control.



I keep getting the error "System.Web.HttpException: The DataSourceID of 'drpGradesEdit' must be the 

ID of a control of type IDataSource.  A control with ID 'sqlDSGradesEdit' could not be found." when 

the grid goes into edit mode

 

One of the columns has a button that fires the Edit command and two have radcombobox + SQLDataSource controls on their Edit templates 

and when I click the edit button I loop through the following bit of code until I get the the item before the one I clicked edit on, and once 

It finishes the sub for that previous item It jumps to my error handling function with the above error message.





Protected

Sub rgUserQuals_RowDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgUserQuals.ItemDataBound

' Check that Item sending the event is a RadGrid Data Item

If (TypeOf e.Item Is Telerik.Web.UI.GridDataItem) Then

'Go through all the Rad grid Items in edit mode and

Dim GridEditableItem As Telerik.Web.UI.GridEditableItem

If (TypeOf e.Item Is Telerik.Web.UI.GridEditableItem) And e.Item.IsInEditMode Then

' Then

Try

Dim teststring As String = ""

teststring = Me.rgUserQuals.MasterTableView.DataKeyValues(e.Item.ItemIndex)("Qualification")

Dim gs As SqlDataSource = CType(e.Item.FindControl("sqlDSGradesEdit"), SqlDataSource)

gs.SelectParameters("Qualification").DefaultValue = _

Me.rgUserQuals.MasterTableView.DataKeyValues(e.Item.ItemIndex)("Qualification")

gs.SelectParameters("QualType").DefaultValue = _

Me.rgUserQuals.MasterTableView.DataKeyValues(e.Item.ItemIndex)("QualType")

Dim cbo As Telerik.Web.UI.RadComboBox = CType(e.Item.FindControl("drpGradesEdit"), Telerik.Web.UI.RadComboBox)

cbo.DataSourceID = gs.ID

cbo.DataBind()

cbo.SelectedValue = Me.rgUserQuals.MasterTableView.DataKeyValues(e.Item.ItemIndex)("Grade")

Dim ss As SqlDataSource = CType(e.Item.FindControl("sqlDSSchoolsEdit"), SqlDataSource)

ss.SelectParameters("SchoolName").DefaultValue = _

Me.rgUserQuals.MasterTableView.DataKeyValues(e.Item.ItemIndex)("SchoolName")

Dim rcbuqes As Telerik.Web.UI.RadComboBox = CType(e.Item.FindControl("rcbUsersQualEditSchool"), Telerik.Web.UI.RadComboBox)

rcbuqes.DataSourceID = ss.ID

rcbuqes.DataBind()

rcbuqes.SelectedValue = Me.rgUserQuals.MasterTableView.DataKeyValues(e.Item.ItemIndex)("SchoolName")

IE7 performance with RadGrid

Hi, I'm using RadGrid, to show a list of components. The problem is, when I tried to click on a record, to enter the edit form, the page takes more than 10-15 seconds only to display the editing form. This issue doesn't happen on Chrome or fxf, in those browsers it only takes 3-4 secs to load the page.

Do you know what I can do to improve the performance on IE??
I already tried disabling pagination, sorting and other features.... I also tried showing only 5 records to see if there's a problem with the qty of data, adding custom pagination to return less results, minimizing Css.

Is there any known issue with IE?

I would really appreciate any help you can give me.

Thanks,
Janise Piombo

Invalid xhtml shape attributes in imagemaps

Hi there,

the value of the shape attribute isn't a well formed xhtml value. The radeditor writes an uppercased value into the shape attribute.

<area shape="RECT" coords="10,10,202,121" href="http://www.google.com" target="_blank" alt="no comment">

If you change the attributes value to a xhtml valid lowercased value, the Image Map Editor doesn't find the area.

Steps for reproducing that

1. Open this Url http://demos.telerik.com/aspnet-classic/editor/examples/ImageMap/DefaultCS.aspx
2. Add the following imagemap code into the editor.

<img style="width: 300px; height: 192px;" usemap="#rade_img_map_RadEditor1_0" src="/aspnet-classic/Editor/Img/UserDir/Marketing/banner.gif" id="Img1" border="0">
<map name="rade_img_map_RadEditor1_0" id="rade_img_map_RadEditor1_0">
<area shape="RECT" coords="10,10,202,121" href="http://www.google.com" target="_blank" alt="no comment">
<area shape="CIRCLE" coords="113,160,21" href="http://www.msdn.com" target="_blank" alt="no comment"></map>

This image map code is editable with the Image Map Editor
3. Change to html view

replace the uppercase "RECT" and "CIRCLE" shapes to "rect" and "circle" the imagemap will be well formed but you can't find the circle shape within the Image Map Editor.

Thanks and best regards
Uwe

Multiple rad windows call to browser window

I have a page that internally opens up a rad window. On that rad window, it opens up a smaller rad window (to enter some options). So Main Window opens Rad Window1 which opens Rad Window2. When Rad Window2 times out, or encounters an error, I try and make a call to a javascript function on Main Window. I thought I could do this using GetRadWindow.BrowserWindow.BrowserWindow.JSCall(), however, that is throwing the same error that GetRadWindow.BrowserWindow.JSCall() is throwing (JSCall is undefined). Is there a way to make this call back to the Main Window from the second Rad Window opened?

Thanks,

Josh

[Solved] How to set timeout on a RadButton in client-side

Hi! Is there a way to set a timeout for disabling a RadButton in the client-side? I would like to disable a RadButton for 5 seconds after a user clicks on it.

Here's the current code I have:

function DisableSubmitBtn() {

var btnSubmit = $find('<% =btnItemSubmit.ClientId %>')

btnSubmit.set_text("Submitting");

btnSubmit.set_enabled(false)

}

I've tried using the window.setTimeout function but it doesn't seem to have any effect. I have tried both:

setTimeout('document.getElementById("' + btnItemSubmit + '").disabled = false', 2000);



var btnSubmit = $find('<% =btnItemSubmit.ClientId %>')

setTimeout('btnSubmit.set_enabled(false)', 2000);

Thanks!

Need Help on RadGrid Drag-and-Drop

Hello,

I'm new to this forum. I see the Drag-and-Drop Row demo, I really like it. I have a similar scenario where my first radgrid (doctorRadgrid) displays all the doctor names (using Linq binds from code behind), and the second radgrid (scheduleRadgrid) contains only doctor names that dragged from the first radgrid. However, when a user drags a doctor name from doctorRadgrid to scheduleRadgrid, I don't want that doctor name deleted from the doctorRadgrid. I just want it copy to the scheduleRadgrid. Is that possible? Can you please provide sample code, I really aprreciated your help.

Thanks in advance!

File Manager ViewPaths location

Hi, as per http://demos.telerik.com/aspnet-ajax/editor/examples/filemanagers/defaultcs.aspx, I have added the line to the web.config file and the entry for Document Manager to the Default.aspx file.

When I click the Document Manager button in the text editor, I always get nothing to choose, i.e., 'Page 1 of 0. Items 1 to 0 of 0'.

The RadEditor Default.aspx file is at e.g. F:/x/xx/xxx/xxxx/RadEditor.Net/Default.aspx and the documents folder is e.g. F:/Assets/Documents - what should I be entering in the line below?

Many thanks

<DocumentManager ViewPaths="~/Assets/Documents" UploadPaths="~/Assets/Documents" DeletePaths="Assets/Documents" />

Ajax request in ASCX control

My structure is this...
MasterPage >> Content Page which includes a RadGrid >> In the RadGrid, I am using a UserControl (ascx) for the insert item.

Masterpage has ScriptManager and RadAjaxManager
Contentpage has RadAjaxProxy
UserControl has RadAjaxProxy

The UserControl is basically a table with labels, Radtextboxes and Radcomboboxes.
My usercontrol has this declaration:
----------------------------------------------------------------------------

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server" >
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="uxDirectory">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="uxProjectName" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>

</telerik:RadAjaxManagerProxy>
-------------------------------------------------------------------------------
uxDirectory and uxProjectName are both RadComboBoxes

The problem I am facing is when a value is changed in the uxDirectory combobox all the "Load" events based on other controls are being fired. It is my understanding that since I have autopostback="true" on the uxDirectory, and based upon the declaration above, that only the uxProjectName control will Load. However, all my controls are reloading. This is wiping out the values saved, etc. How can I perform a Ajax postback for a specific control within a ASCX Usercontrol?

Numeric Value is null on Insert and Update

All,

I am trying to do an insert/update of a numeric value. I have identical code in another control working just fine. All attempts to insert or update result in OriginalAmount being null. I have tried using a bound column and a numeric column with the same failure.

Any and all help is greatly appreciated. I cannot understand how this was working before and now does not, and another control with identical grid and code is fine.

Thanks,
Bruce
