[Solved] find a control in radscheduler inlinetemplate using javascript

[utchi]

Hi,

I need to find a radcombo and update its collection using javascript.

Please check with the coding given below, it showing error message, 'null object' for Radcombo2,

function

 

clientselectedindexchanged(sender,e) // Radcombo1 selected index change

 

 

 {

 

var item = e.get_item();

 

 

 

var comboItem = sender.get_text();

 

 

 

if(comboItem == 'Cancel Episodes')

 

 

 {

 

var combo= $find('<%= Radcombo2.ClientID %>');

 

 

 

 

var

 

comboItem1 = new Telerik.Web.UI.RadComboBoxItem();

 

 

 

 comboItem1.set_text(

'welcome');

 

 

 combo.get_items().add(comboItem1);

comboItem1.select();

 

combo.trackChanges();

 

 

 combo.commitChanges();

 

 

}
}

Please give any suggestion.

Thanks in advance.

Hi Utchimahali,

You can save the ClientID in a HiddenField and then access the second combobox using the saved HiddenField value as shown below.

ASPX:

 <InlineInsertTemplate>
        <telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged">
            <Items>
                <telerik:RadComboBoxItem Text="Item1" />
                <telerik:RadComboBoxItem Text="Item2" />
            </Items>
        </telerik:RadComboBox>
        <telerik:RadComboBox ID="RadComboBox2" runat="server">
        </telerik:RadComboBox>
    </InlineInsertTemplate>

CS:

    protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatedEventArgs e)
    {
        if (e.Container.Mode == SchedulerFormMode.Insert)
        {
            RadComboBox cb1 = (RadComboBox)e.Container.FindControl("RadComboBox1");
            RadComboBox cb2 = (RadComboBox)e.Container.FindControl("RadComboBox2");
            HiddenField1.Value = cb2.ClientID;
        }
    }

JavaScript:

<script type="text/javascript">
    function OnClientSelectedIndexChanged() {
        var hf = document.getElementById("HiddenField1");
        var combo2 = $find(hf.value);
        alert(combo2.get_items().get_count());
    }
</script>

hi,

Thanks for ur help, but doesn't work.

Please find the attached screenshot it showing error, value store in hiddenfield and code modified as given below,

function

 

clientselectedindexchanged(sender,e)

 

{

 

 

var item = e.get_item();

 

 

var comboItem = sender.get_text();

 

 

if(comboItem == 'Cancel Episodes')

 

{

 

 

var hf = document.getElementById("cmb_cancelepisode");

 

 

var cmb_cancelepisode = $find(hf.value);

 

alert(cmb_cancelepisode.get_items().get_count());

 

var comboItem = new Telerik.Web.UI.RadComboBoxItem();

 

 

comboItem.set_text(

'welcome');

 

 

cmb_cancelepisode.get_items().add(comboItem);

comboItem.select();

comboItem.set_text(

'welcome1');

 

cmb_cancelepisode.trackChanges();

 

cmb_cancelepisode.commitChanges();

comboItem.scrollIntoView();

 

 

}
}

and in cs file,

 

RadComboBox

 

ComboEpisode = (RadComboBox)e.Container.FindControl("cmb_CancelingOptions");

 

cmb_cancelepisode.Value = ComboEpisode.ClientID;

 

Please give any suggstion to solve it.
