Missing Axis Labels on Save

When I save the displayed chart image with the code below, the axis labels are missing from the image (I saw on an earlier post this can happen if scroll mode is on). I am not using scroll mode

Here is the code

Dim

ms1 As New System.IO.MemoryStream()

Me.chtGraph.Save(ms1, System.Drawing.Imaging.ImageFormat.Png)

Me.Page.Response.Clear()

Me.Page.Response.ClearHeaders()

Me.Page.Response.AddHeader("Content-disposition", "attachment; filename=graph.png")

Me.Page.Response.AddHeader("Content-type", "image/png")

Me.Page.Response.BinaryWrite(ms1.ToArray())

Me.Page.Response.[End]()

Element 'Grid DropDownColumn' is not a known element

I am building a Grid using the Q1 2010 RadGrid control, and 

using Template Form Update as my guide. 



I have a Template edit form, and I'm having an issue when 

trying to add a Telerik Grid Dropdown Column.

I am getting an error saying that the Grid Dropdown 

Column is not a known element.



Below is a copy of my edit form template:

RadGrid with dynamical and programatic creation of GridDropDownColumns and ObjectDataSources

Dear technology architects:

I need an expert voice to resolve my problem.
I have a RadGrid with AutoGeneratedColumns = "False", but I add programatically the columns. There are BoundColumns and GridDropDownColumn.

The GridDropDownColumns are generated dynamically because I don't know how many columns will come from the grid datasource. Then I have the following code in the Page_Load:

int ContCatalogos = 0;

RadGridSabana.MasterTableView.Columns.Clear();

foreach (DataColumn dataColumn in dtSabana.Columns)

{

ContCatalogos++;

switch (ContCatalogos)

{

case 1:

dsCatalogos1.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos1.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 2:

dsCatalogos2.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos2.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 3:

dsCatalogos3.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos3.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 4:

dsCatalogos4.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos4.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 5:

dsCatalogos5.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos5.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 6:

dsCatalogos6.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos6.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 7:

dsCatalogos7.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos7.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 8:

dsCatalogos8.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos8.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 9:

dsCatalogos9.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos9.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 10:

dsCatalogos10.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos10.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 11:

dsCatalogos11.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos11.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 12:

dsCatalogos12.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos12.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 13:

dsCatalogos13.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos13.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 14:

dsCatalogos14.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos14.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

case 15:

dsCatalogos15.SelectParameters[0].DefaultValue = "1"; //Empresa

dsCatalogos15.SelectParameters[1].DefaultValue = dataColumn.ColumnName; //Catalogo

break;

}

GridDropDownColumn dropdownColumn = new GridDropDownColumn();

this.RadGridSabana.MasterTableView.Columns.Add(dropdownColumn);

dropdownColumn.DataField = dataColumn.ColumnName; //Una columna del DataSource del grid.

dropdownColumn.ListValueField = dataColumn.ColumnName;

//La columna de la funcion que trae los valores para llenar el combo.  Esta columna debe tener los mismos valores que Datafield para que se relacione.

dropdownColumn.DataSourceID = "dsCatalogos" + ContCatalogos.ToString(); //El nombre del DataSource

dropdownColumn.ListTextField = dataColumn.ColumnName; //Es la columna del datasource del Combo que contiene el nombre a desplegar

//dropdownColumn.UniqueName = dataColumn.ColumnName;

dropdownColumn.HeaderText = dataColumn.ColumnName;

}

I have to create an independent ObjectDataSource for each GridDropDownColumn. If I don't know how many columns could be retrieved I have to create more than 15 ObjectDataSourcse manually in the code.
If the grid datasource contains more than 15 columns, I have a problem...

Following the code in the ASPX

<asp:ObjectDataSource ID="dsCatalogos1" runat="server" TypeName="BusinessLayer.Funciones"

SelectMethod="ConsultarItemsCatalogo"

OldValuesParameterFormatString="original_{0}" >

<SelectParameters>

<asp:ControlParameter ControlID="RadGridSabana" Name="Empresa" PropertyName="SelectedValue" Type="Int32" />

<asp:ControlParameter ControlID="RadGridSabana" Name="NombreCatalogo" PropertyName="SelectedValue" Type="String" />

</SelectParameters>

</asp:ObjectDataSource>

<asp:ObjectDataSource ID="dsCatalogos2" runat="server" TypeName="BusinessLayer.Funciones"

SelectMethod="ConsultarItemsCatalogo"

OldValuesParameterFormatString="original_{0}" >

<SelectParameters>

<asp:ControlParameter ControlID="RadGridSabana" Name="Empresa" PropertyName="SelectedValue" Type="Int32" />

<asp:ControlParameter ControlID="RadGridSabana" Name="NombreCatalogo" PropertyName="SelectedValue" Type="String" />

</SelectParameters>

</asp:ObjectDataSource>

<asp:ObjectDataSource ID="dsCatalogos3" runat="server" TypeName="BusinessLayer.Funciones"

SelectMethod="ConsultarItemsCatalogo"

OldValuesParameterFormatString="original_{0}" >

<SelectParameters>

<asp:ControlParameter ControlID="RadGridSabana" Name="Empresa" PropertyName="SelectedValue" Type="Int32" />

<asp:ControlParameter ControlID="RadGridSabana" Name="NombreCatalogo" PropertyName="SelectedValue" Type="String" />

</SelectParameters>

</asp:ObjectDataSource>

<asp:ObjectDataSource ID="dsCatalogos4" runat="server" TypeName="BusinessLayer.Funciones"

SelectMethod="ConsultarItemsCatalogo"

OldValuesParameterFormatString="original_{0}" >

<SelectParameters>

<asp:ControlParameter ControlID="RadGridSabana" Name="Empresa" PropertyName="SelectedValue" Type="Int32" />

<asp:ControlParameter ControlID="RadGridSabana" Name="NombreCatalogo" PropertyName="SelectedValue" Type="String" />

</SelectParameters>

</asp:ObjectDataSource>

<asp:ObjectDataSource ID="dsCatalogos5" runat="server" TypeName="BusinessLayer.Funciones"

SelectMethod="ConsultarItemsCatalogo"

OldValuesParameterFormatString="original_{0}" >

<SelectParameters>

<asp:ControlParameter ControlID="RadGridSabana" Name="Empresa" PropertyName="SelectedValue" Type="Int32" />

<asp:ControlParameter ControlID="RadGridSabana" Name="NombreCatalogo" PropertyName="SelectedValue" Type="String" />

</SelectParameters>

</asp:ObjectDataSource>

<asp:ObjectDataSource ID="dsCatalogos6" runat="server" TypeName="BusinessLayer.Funciones"

SelectMethod="ConsultarItemsCatalogo"

OldValuesParameterFormatString="original_{0}" >

<SelectParameters>

<asp:ControlParameter ControlID="RadGridSabana" Name="Empresa" PropertyName="SelectedValue" Type="Int32" />

<asp:ControlParameter ControlID="RadGridSabana" Name="NombreCatalogo" PropertyName="SelectedValue" Type="String" />

</SelectParameters>

</asp:ObjectDataSource>

the DataSources are equal each other, the unique difference is the ID. They call to the same function that receives the same parameters but with different values.
If you take a look in the code behind, I have to insert a switch instruction to give them the parameter values.

My question is:

Is there a way to do the same thing creating the ObjectDataSources dynamically and assign them to theGridDropDownColumns in the code behind?

It could be more elegant and more efficient.

Please help me with this problem.

Thanks

[Solved] Grid with Detail Tables question

Hello, I have a Radgrid with a DetailTable inside. This Grid has orders with order items in the detail table.
I have a OnDataBound event on this Grid. This event checks for the value in a column and then sets the row backcolor on it.
It works fine until I try to expand into the detailtable since then it tries to execute the OnDatabound event and the field I am checking does not exists in the detail table.
Below is the OnDataBound event:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem dataItem = (GridDataItem)e.Item;

TableCell myCell = dataItem["ready"];

if ((myCell.Text == "True"))

{

dataItem.BackColor = System.Drawing.Color.SteelBlue;

}

The code fails when trying to expand into the detail table. It fails on line:
TableCell myCell = dataItem["ready"];
since the "ready" column does not exist in the detail table.

Can someone let me know how I can fix this?
Thanks.

[Solved] Validation in EditItemTemplate

I am attempting to add a CustomValidator to a control in an EditItemTemplate, but cannot figure out how to get the values of the two objects involved in the OnServerValidate event. Have googled for information half a day with no success.

Based on a value entered in a TextBox with validation, I need to determine if a value exists in a RadDatePicker inside all within an EditItemTemplate. (edit mode)

Thanks,
