Jill-Connie Lorentsen asked on 07 Sep 2012, 11:44 AM

I have a RadGrid where one of the columns is a GridTemplateColumn with a RadComboBox:

<telerik:RadGrid ID="EmployeeRadGrid" runat="server" Width="96%" GridLines="None"

AutoGenerateColumns="False" PageSize="13" AllowSorting="True"

AllowPaging="True" ShowStatusBar="true" Visible="False"

OnUpdateCommand="EmployeeRadGrid_UpdateCommand"

OnNeedDataSource="EmployeeRadGrid_NeedDataSource"

OnInsertCommand="EmployeeRadGrid_InsertCommand"

OnDeleteCommand="EmployeeRadGrid_DeleteCommand"

onitemdatabound="EmployeeRadGrid_ItemDataBound"

>

<PagerStyle Mode="NextPrevAndNumeric"></PagerStyle>

<MasterTableView DataKeyNames="EmployeeID" AllowMultiColumnSorting="True" Width="100%"

CommandItemDisplay="Top" EditMode="InPlace">

<Columns>

<telerik:GridBoundColumn UniqueName="Name" SortExpression="Name" HeaderText="Navn"

DataField="Name" />

<telerik:GridTemplateColumn UniqueName="EmployeeID" HeaderText="Departement">

<ItemTemplate>

<%#DataBinder.Eval(Container.DataItem, "DepartementName")%>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadComboBox runat="server" ID="RadComboBox1" Width="200"

DataTextField="Name" DataValueField="DepartementID" DataSourceID="DepartementDataSource"

AllowCustomText="False" EnableAutomaticLoadOnDemand="true" OnClientLoad="OnClientLoadHandler">

</telerik:RadComboBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

The RadComboBox1 is populated through the ItemDataBound event of the EmployeeRadGrid:

protected void EmployeeRadGrid_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.IsInEditMode)

{

GridEditableItem item = (GridEditableItem)e.Item;

if (!(e.Item is IGridInsertItem))

{

RadComboBox combo = (RadComboBox)item.FindControl("RadComboBox1");

combo.Items.Clear();

List<DepartementResult> deps = getDepartements();

foreach (DepResult dep in deps)

{

RadComboBoxItem newItem = new RadComboBoxItem();

newItem.Text = dep.Name;

newItem.Value = dep.DepartementID.ToString();

newItem.Attributes.Add("DepartementName", dep.Name);

combo.Items.Add(newItem);

newItem.DataBind();

}

combo.SelectedValue = ((DepartementResult)e.Item.DataItem).DepartementID.ToString();

}

I also have another RadGrid, where all the departements are listed, and the user can make changes to them.

What I want is that the departements listed in RadComboBox1 are updated after changes are made in the DepartementRadGrid. Now what happens is that the RadComboBox1 is disabled in a way, - nothing happens if I click on it. The other column in the EmployeeRadGrid is editable.

If I open my page and go straight to the EmployeeRadGrid, I can access the RadComboBox1, and change the departement. But if I make changes in the EmployeeRadGrid, the RadComboBox is not responsive.

Any help is appreciated.

Hello Jill,

Thanks for the code. I am afraid you are taking the wrong approach to that requirement. When you update the departments data source you should rebind the employees grid and then put the item that was in edit mode back into edit mode. That means that you need a way to track which item is currently being edited in the employees grid. Furthermore, I noticed that you are binding the combo both to a DataSource control and a collection of department items. You have to use either of those - I believe this is the reason why the combo becomes unresponsive.

Hope it helps.

I am not sure I understand what you mean, or if I have explained the problem correctly.

I've tried removing the combobox' dataSourceID from markup, and only binding to the list of departements, without any success.

I don't understand what you say about putting the item back in edit mode. The combo box in the EmployeesRadGrid is not neccessarily being edited when this happens. If I edit the departements, the combobox in the employees grid becomes unresponsive, and if I don't the combobox behaves as expected.

It is only the combobox that becomes unresponsive, not the other column.

Hello Jill,

I see that you have handled the OnClientLoad event of the combobox and you set there its input element to readonly. This might be the reason why the combo is disabled. You can remove this and instead use the AllowCustomText to determine whether the user is allowed to write inside the textbox of the combo or not.
Also when you use automatic load on demand you should bind it using the DataSourceID property. To achieve the desired effect both the combobox and the DepartementRadGrid should be databound to the same datasource. So when you change the datasource using the grid the changes will be reflected in the combo when you click on it to open the dropdown section.

I hope this helps.

Kind regards,

Hello,

I am attaching a sample page that shows how you can achieve this requirement. In the page you can check that when you edit a record in the Department grid and then open the combo in the Employees grid it will show the correct value. For simplicity the page only stores changes in the session and the update command is implemented only for the Department grid. Also the combo is set not to allow custom user input but it is responsive and you can pick values.

I see that you have also opened a support ticket on the same issue so in order to avoid duplicate posts we will continue any further communication there.

All the best,
Marin
