RadComboBox Check All on Databind

[Ronald]

I have a RadComboBox with miltiselect checkboxes.

<telerik:RadComboBox ID="rcbCAMs" runat="server" AppendDataBoundItems="true" CheckBoxes="true" EnableCheckAllItemsCheckBox="true" Skin="WebBlue"                      Width="200px" OnSelectedIndexChanged="rcbCAMs_SelectedIndexChanged" AutoPostBack="true" ></telerik:RadComboBox>

I'm binding the RadComboBox with a databind in C#

protected void BindToDataTableCAMs(RadComboBox combo)
        {
            CAPData dataSet = new CAPData();
            DataTable dtCAMs = new DataTable();
            dtCAMs = dataSet.GetProjectCAMs(tbProjects.Text);

            if (dtCAMs.Rows.Count != 0)
            {
                combo.DataTextField = "Manager";
                combo.DataValueField = "Manager";
                combo.DataSource = dtCAMs;
            }

            combo.DataBind();
        }

 

How do I set the default to be Check All on the initial load?

Hi Ronald,

You can achieve this requirement using the following approach:

RadComboBox1.DataBind();
foreach (RadComboBoxItem item in RadComboBox1.Items)
{
    item.Checked = true;
}

I hope this will prove helpful.
