Hi,

I am using two RadComboBox in SharePoint environment inside update panel. The control is inside a user control web part. The problem is when we switch to ie 7, these combo boxes disappear randomly. I tried to apply position:relative to its parent div but this does not solve the issue. Please help.

Thanks and regards.

RadListBox validation that items exist when used as a transfer destination

I have a set of RadListBox es used to select categories. I want to validate that the transfer destination has items. I can get this to work but not when the control to validate is the RadListBox. Seems like I have to validate a text box to get the Validator to fire client side. If the text box is not changed or is valid then the RadListBox does not get validated until the server side (which is better than never). Is it possible to get the Validator to fire another time even if it is just on the submit button? Here is the code:

Available Sub Categories<br />

<telerik:RadListBox ID="rlbAvailableSubcategories" runat="server" Height="200px"

Width="200px" AllowTransfer="true" TransferToID="rlbMappedSubcategories" TransferMode="Copy"

ButtonSettings-ShowTransferAll="false" SelectionMode="Multiple" AllowDelete="false" AllowTransferOnDoubleClick="True" ButtonSettings-TransferButtons="TransferFrom">

</telerik:RadListBox>

Mapped<br />

<telerik:RadListBox ID="rlbMappedSubcategories" runat="server" AllowTransferDuplicates="false"

Height="200px" Width="200px" AllowDelete="true">

</telerik:RadListBox>

<asp:CustomValidator ID="ValidateMappedSubcategories" EnableClientScript="True" runat="server" ErrorMessage="You must add at least 1 category"

ClientValidationFunction="rlbMappedSubcategoriesHasItems" ControlToValidate="txtAddLongDesc" ValidateEmptyText="True" OnServerValidate="rlbMappedSubcategoriesHasItems_Validate" Display="Dynamic"></asp:CustomValidator>

<script type="text/javascript">

function rlbMappedSubcategoriesHasItems(source, args) {

var list = $find("<%= rlbMappedSubcategories.ClientID %>");

args.IsValid = list.get_items().get_count() > 0;

}

</script>

[Solved] Paging to the top of the grid

H, guys

I have this nice piece of code that ensures that when the grid is paged it will jump back to the top of the grid. Useful for when the user is at the bottom of the grid.

<script type="text/javascript" language="javascript">

// Catches events fired by the RadGrid (paging) and jumps page to the top

var postbackElement;

Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginRequest);

Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(pageLoaded);

function beginRequest(sender, args) {

postbackElement = args.get_postBackElement();

}

function pageLoaded(sender, args) {

if (typeof (postbackElement) === "undefined") {

return;

}

// Uses the MasterTable ClientID

if ((postbackElement.id) === "ctl00_CphJam_ctl00_RadGrid1_ctl00") {

window.scrollTo(0, 160);

}

</script>

However, it only works when a page 'number' is clicked - it does not work when any of the next, previous, first or last image buttons are clicked.

Does anybody know please?

Cheers,
Jon

Fields with errors with red borders

Hi!

I have fowlling insert command

void RadGrid1_InsertCommand(object sender, GridCommandEventArgs e)

{

........

var result = blala.ValidateAndSave(...);

if (result.ResultCode == ValidationResultCode.Ok)

{

AddMessage("The data were successfully validated and Saved!");

NewAllEntriesToAccount();

}

else

{

AddMessage("Please check the data. The following errors were found: "

);

                            AddErrorList(RadGrid1.Columns[meldung.SpaltenIndex].UniqueName);

}

If the valditaion with errors, i want to change the border color of the field in the Grid Editor red. In which fields the errors are known to me.
I have tried to do this in the RadGrid1_ItemCreated event, but the event fires before the InsetCommand:

GridEditableItem item = (GridEditableItem)e.Item;

TextBox combo = (TextBox)item[itemm.ItemArray[0].ToString().Replace(" ", "")].Controls[0];

combo.BackColor = GetColor((ClArt)itemm.ItemArray[2]);

if (IsInErrorList(itemm.ItemArray[0].ToString().Replace(" ", "")))

{

combo.BorderStyle = BorderStyle.Solid;

combo.BorderWidth = 2;

combo.BorderColor = System.Drawing.Color.Red;

}

Have anyone a idea, how i can do this ?

Thank you very much

I can create and rename folders, but not delete them

I am using the Rad FileExplorer built into Dotnetnuke 6. I have successfully used this in several sites. However, in the site I'm working on now the FileExplorer allows me to create, rename and move folders, but I can't delete them. I have tried it with partial rendering on and off. I have written as sub to do a full permissions test. The permissions test creates a folder, creates a file in the folder, deletes the file, then deletes the folder and it all passes without a problem. Still, the Rad FileExplorer can't seem to delete folders. Bizarre. Any else have this problem?
