RadList with ComboBox

[Nicole]

Hi

I have a RadListView with a RadComboBox in the fieldset itemtemplate, and the RadComboBox has a CheckBox ItemTemplate.

What I’m need to do is to change the text of the first item in my combobox and hide the checkbox.

It works fine if I have only one combobox but I need this in a ListView.
Thanks,
Nicole

protected void RadListView1_ItemDataBound(object sender, RadListViewItemEventArgs e)

{

RadComboBox cmbColores = (RadComboBox)e.Item.FindControl("cbmColores1");

DataTable dt = CargarCombos();

//Add Item

dt.Rows.Add(-1, "");

DataView dv = new DataView();

dv = dt.DefaultView;

dv.Sort = "NombreCompleto";

DataTable dt1 = dv.ToTable();

cmbColores.DataSource = dt1;

cmbColores.DataTextField = "NombreCompleto";

cmbColores.DataValueField = "SKUID";

cmbColores.DataBind();

//change text: first item combobox

cmbColores.FindItemByValue("-1").Text = " -- Seleccione --";

RadComboBoxItem item = cmbColores.FindItemByValue("-1");

CheckBox chk = (CheckBox)item.FindControl("chk1");

//first item combobox

chk.Visible = false;

}

Hello Nicole,

I have tested your code locally and seems to be working just fine. Please check the attachment to this post.

Hi, thanks for your help.
I'm getting this error: Compiler Error Message: CS1525: Invalid expression term '>' , (I think is the Framework Version).

Line 44: protected void RadListView1_NeedDataSource(object sender,RadListViewNeedDataSourceEventArgs e) Line 45: { Line 46: RadListView1.DataSource = Enumerable.Range(0, 2).Select(i => i);Line 47: } Line 48: }

Microsoft (R) Visual C# 2005 Compiler version 8.00.50727.3053
for Microsoft (R) Windows (R) 2005 Framework version 2.0.50727

Also when I test it in my page the dropdownlist has values but the checkbox of the first item isn't visible=false.

Hello Nicole,

Simply bind RadGrid to collection. It really doesn't matter in this particular case. In the demo I am using .NET 3.5 Enumerable.
For example:

protected void RadListView1_NeedDataSource(object sender,RadListViewNeedDataSourceEventArgs e)
{
        RadListView1.DataSource = new object[] { 1,2,3  };
}

You will see that first item checkbox is hidden.
