Hi, I'm trying to bind a RadComboBox with an ObjectDataSource (odsFuenteEmisionAlcance) that returns a List of Objects like these:
This is my ComboBox
I'm trying to use the DataTextField and DataValueField values from the Property FuenteEmision, but somehow is not getting it, this is what I get:
Like I show before the object FuenteEmisionAlcance does a have a FuenteEmision property, the combo is able to find it, i've tried using only DataTextField="FuenteEmision" and DataValueField="FuenteEmision" just to try and it does find it, but when it comes to find a property from the property it crashes, is this impossible? or there is another way I can acomplish this.
List<FuenteEmisionAlcance>public class FuenteEmisionAlcance{ private FuenteEmision m_FuenteEmision; private Alcance m_Alcance; public FuenteEmision FuenteEmision { get { return m_FuenteEmision; } set { m_FuenteEmision = value; } } public Alcance Alcance { get { return m_Alcance; } set { m_Alcance = value; } }}This is my ComboBox
<telerik:RadComboBox ID="rcbFuenteEmision" runat="server" AutoPostBack="True" DataSourceID="odsFuenteEmisionAlcance" DataTextField="FuenteEmision.Nombre" DataValueField="FuenteEmision.Id" ZIndex="100000" CausesValidation="False" OnSelectedIndexChanged="rcbFuenteEmision_SelectedIndexChanged" EmptyMessage="--Seleccione--" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged" OnDataBinding="rcbFuenteEmision_DataBinding"></telerik:RadComboBox>
I'm trying to use the DataTextField and DataValueField values from the Property FuenteEmision, but somehow is not getting it, this is what I get:
[NotSupportedException: Object of type HUC.FuenteEmisionAlcance does not have a FuenteEmision.Nombre property.]Like I show before the object FuenteEmisionAlcance does a have a FuenteEmision property, the combo is able to find it, i've tried using only DataTextField="FuenteEmision" and DataValueField="FuenteEmision" just to try and it does find it, but when it comes to find a property from the property it crashes, is this impossible? or there is another way I can acomplish this.

I would like to know how to hide the Up button when it reaches the first position as it cannot be moved up further.
Similarly to hide the down button when it reaches the last position as it cannot be moved down further
Please advise.

I am having issues using the AsynUpload control and .ascx files. It's almost like it doesn't work with them at all. I try to use the clientside development and the server side development and either I get errors or it just doesn't fire. What can I do to alleviate this issue?

Hello!
The property DatePopupButton-ToolTip of RadDatePicker does not work.
"Open the calendar popup." cannot be changed to empty string.
Please don't give me an answer with the javascript method. This is not the solution!
Maybe you have at least a css rule!
Thanks!

I need to change the formatting of some of the field in the row/record if one of them contains any value.
I tried this:
if (e.Item is GridDataItem)
{
GridDataItem dataBoundItem = e.Item as GridDataItem;
if ((dataBoundItem["AlternCost"].Text) != null)
{
dataBoundItem["AlternCost"].ForeColor = Color.Red;
dataBoundItem["AlternCost"].Font.Bold = true;
dataBoundItem["AlternCost"].BackColor = Color.Yellow;
dataBoundItem["TotCost"].ForeColor = Color.Red;
dataBoundItem["TotCost"].Font.Bold = true;
}
}
but I am experiencing problems because the back color applies to the entire column if the condition is true and I need it to be applied only to the "AlternCost" cell/row of the record where the condition occurs.
Please help!
Thanks

I have a radgrid with 4 columns:
Quantity, Cost, SpecialCost, TotalCost
The first 3 columns are data bound, the 4td column is a Calculated column.
I need to calculate the value of the TotalCost based on Quantity*Cost, this is easy:
DataFileds: Quantity, Cost
Expression: {0}*{1}
but if the SpecialCost cell contains a value then the calculation should be done using SpecialCost*Quantity.
As far as I know, the Expression editor does not take logical functions otherwise I could simply use an if statement to check if SpecialCost contains a value and select it.
How can I achieve the above?
