[Solved] Retrieving the Value On SelectedIndexChange

I am having an issue trying to get the RadComboBox's Selected Value on the SelectedIndexChanged event. The odd thing is that during the SelectedIndexChanged event when I check e it has the old value (e.OldValue) and the old text (e.OldText) but the e text (e.Text) shows up correctly but the e.Value turns to null or "". Why is my selected value turning to an empty string/null on SelectedIndexChange?

See my code below. Thanks for any help.

[Solved] Items display with padding

Hello,

I'm a new customer of Telerik and I'm using the ListBox tool for the first time. When I add items to the ListBox they're displayed with about 20 pixels of padding along the left-edge.

It looks like this:
http://screencast.com/t/ZjM0NTUzMDIt

How do I adjust that? At first I thought the ListBoxItems needed to have "Checkable" set to false, but that didn't do the trick.

Other suggestions?

Thanks,

Michael

   There are cases when the grid is sorted. In that request, i dont want to go to the database.
   How ever, when the refresh button is pressed or the grid is loaded for the first time, I want to go to the database.

   How can i identify the difference between these 2 requests.

Currently the signature of the function is

public

static List<Employee> getAllEmployee(string sortExpression)
{..}
comming from object datasource mapped to the grid

    
            <asp:ObjectDataSource ID="dsEmployee" runat="server" SelectMethod="getAllEmployee" 
        
                    TypeName="Employee" DataObjectTypeName="Employee"

Databound menu and separator

Hi, I am generating a menu in code using a data schema I have defined for this purpose. All works well, but I'm having trouble making the separator appear. I'm trying to do this in the ItemDatabound method. The result is that the menu displays with the separator occupying space, but no horizontal line appears. The code is below, you can ignore the menu access code, the first part of the method is where this happens. Note: menu item text of a single dash "-" indicates that the item is a separator. I'm using the Default skin.

                        protected void RadMenuIW_ItemDataBound(object sender, RadMenuEventArgs e)         
                {

                    e.Item.Visible = (item.Hidden == null) || !((bool) item.Hidden);         
                    e.Item.Enabled = (item.Disabled == null) || !((bool) item.Disabled);

Grid DetailTable Sorting

Everytime I click a header in the detailtable to sort, the entire detail table collapses. Am I doing something wrong? Most of the code I have are just copy paste from the demos.

<telerik:RadGrid ID="grdDataView" runat="server" EnableEmbeddedBaseStylesheet="false"

onprerender="grdDataView_PreRender" ShowStatusBar="false" OnNeedDataSource="grdDataView_OnNeedDataSource"

AutoGenerateColumns="False" PageSize="4" AllowSorting="True" AllowMultiRowSelection="False" PagerStyle-ShowPagerText="false"

AllowPaging="True" GridLines="None" EnableEmbeddedSkins="false" Skin="emmawebskin" Width="3500px" PagerStyle-Font-Underline="false"

ondetailtabledatabind="grdDataView_DetailTableDataBind" OnSortCommand="grdDataView_OnSortCommand">

<telerik:GridTableView DataKeyNames="EquipmentID" Width="100%"

runat="server">

<telerik:GridBoundColumn SortExpression="XXXXXXXX" HeaderText="XXXXXXXX" HeaderButtonType="TextButton"

DataField="XXXXXXXX" UniqueName="XXXXXXXX">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="XXXXXXXX" HeaderText="XXXXXXXX" HeaderButtonType="TextButton"

DataField="XXXXXXXX" UniqueName="XXXXXXXX">

</Columns>

<telerik:GridSortExpression FieldName="XXXXXXXX"></telerik:GridSortExpression>

</SortExpressions>

</telerik:GridTableView>

</DetailTables>

<telerik:GridBoundColumn SortExpression="XXXX" HeaderText="XXXX" HeaderButtonType="TextButton"

DataField="XXXX" UniqueName="XXXX" >

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="XXXXXX" HeaderText="XXXXXX" HeaderButtonType="TextButton"

DataField="XXXXXX" UniqueName="XXXXXX" Visible="false">

</telerik:GridBoundColumn>

</Columns>

<telerik:GridSortExpression FieldName="XXXX"></telerik:GridSortExpression>

</SortExpressions>

</MasterTableView>

</telerik:RadGrid>

protected void grdDataView_OnSortCommand(object source, GridSortCommandEventArgs e)

{

GridSortExpression sortExpr = new GridSortExpression();

switch (e.OldSortOrder)

{

case GridSortOrder.None:

sortExpr.FieldName = e.SortExpression;

sortExpr.SortOrder = GridSortOrder.Ascending;

e.Item.OwnerTableView.SortExpressions.AddSortExpression(sortExpr);

break;

case GridSortOrder.Ascending:

sortExpr.FieldName = e.SortExpression;

sortExpr.SortOrder = GridSortOrder.Descending;

e.Item.OwnerTableView.SortExpressions.AddSortExpression(sortExpr);

break;

case GridSortOrder.Descending:

sortExpr.FieldName = e.SortExpression;

sortExpr.SortOrder = GridSortOrder.Ascending;

e.Item.OwnerTableView.SortExpressions.AddSortExpression(sortExpr);

break;

}

e.Canceled = true;

grdDataView.Rebind();

}
