[Solved] problem in get selectedItems when use AutoCompleteSeparator

[Sepideh Ghanbari]

I have a combobox with AutoCompleteSeparator=";" and use ItemsRequested for load data ,after select multi items the Text property is correct but SelectedValue property has only last selectedItem value .How can i get SelectedItems or selectedValues in combobox?

Hi Sepideh,

The SelectedValue property will return the value of the last selected item if you are using AutoCompleteSeperator for radcombobox. If you need to get the values of all the selected items, you should get the text of the input field, and split the string by ";" and find the items by text (FindItemByText) to get the values of the items. See the example shown below.

C#:

protected void Button1_Click(object sender, EventArgs e)

{

string[] array = new string[10];

string value="";

int i =0;

string text = RadComboBox1.Text.ToString();

for(i = 0; text.Contains(";");i++)

{

string sub = text.Split(';')[0];

text = text.Substring(text.IndexOf(';')+1);

array[i] = (RadComboBox1.FindItemByText(sub) as RadComboBoxItem).Value.ToString();

}

array[i] = (RadComboBox1.FindItemByText(text) as RadComboBoxItem).Value.ToString(); // Array contains selected values

}

Here I used an array to keep the selected item values.

Hi Shinu
Thanks for your reply but I use ItemsRequested event for load data and "FindItemsbyText" return null because combobox Items is null. my code is like this :

<telerik:RadComboBox ID="RadComboBox1"  AutoPostBack="true"

Runat="server" ShowToggleImage="True" ShowMoreResultsBox="false"

EnableLoadOnDemand="True" MarkFirstMatch="true" Width="300" Height="100"

DataTextField="DisplayString" DataValueField="ParticipantID"

HighlightTemplatedItems="true" ShowDropDownOnTextboxClick="false"

onitemsrequested="RadComboBox1_ItemsRequested"

CssClass="CommonText" AutoCompleteSeparator="-" AllowCustomText="false"  >

<CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>

</telerik:RadComboBox>  protected void RadComboBox1_ItemsRequested(object o, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e) { string[] text = e.Text.Split(';'); var list = LoadData(text[text.Length - 1]); if (list != null) { RadComboBox1.SelectedValue = ""; RadComboBox1.DataSource = list; RadComboBox1.DataBind(); } }

Do you have any other solution?
