[Solved] OnSelectedIndexChanged does not fire.

Hi

I am new to the RadControls, but I am enjoying using them.

I have an issue with the OnSelectedIndexChanged event not firing and running the codebehind. I have it working with the standard Microsoft control but can't seem to get this one going.

Below is the code I currently have.

Thanks for your assistant.

radio button doesn't fire even with autopostback

<asp:RadioButton ID="rb_yes" runat="server" GroupName="test" Text="Yes" AutoPostBack="true" />
<asp:RadioButton ID="rb_no" runat="server" GroupName="test" Text="No" AutoPostBack="true" />

the above works fine and it does go into the
checkedchanged function.

however, when i put
<telerik:radajaxmanager id="RadAjaxManager1" runat="server" UpdatePanelsRenderMode="Inline" >
            <ClientEvents OnRequestStart="RequestStart" />
            <AjaxSettings>
                 <telerik:AjaxSetting AjaxControlID="rb_yes">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="pnl_Test" LoadingPanelID="RadAjaxLoadingPanel1" />
                        <telerik:AjaxUpdatedControl ControlID="txt_imageurl" />
                        <telerik:AjaxUpdatedControl ControlID="txt_imagename" />
                        <telerik:AjaxUpdatedControl ControlID="btn_uploadImage" />
                    </UpdatedControls>
                </telerik:AjaxSetting>

I have a case where RadButton Changes checked value. I run though the behind code. the RadButton is checked. Then it appears as unchecked. I am using ajax. I cant seem find out when it is changing the value. any ideas. Also in IE the page renders much slower and I will see the checked values for a second then it changes to unchecked.

Also, Is there a way to debug the ajax to see if the issue is coming form that?

How do you set the DisabledStyle for a ComboBox in Code Behind?

I tried this but it didn't work:

[ToolboxData("<{0}:RadComboBoxEx runat='server'></{0}:RadComboBoxEx>")]

public class RadComboBoxEx : RadComboBox

{

public RadComboBoxEx()

: base()

{

//this.DisabledStyle.BackColor = System.Drawing.Color.White;

//this.DisabledStyle.ForeColor = System.Drawing.Color.LightGray;

this.Init += new EventHandler(RadComboBoxEx_Init);

}

void RadComboBoxEx_Init(object sender, EventArgs e)

{

SetDisabledStyle(this.Controls);

}

private void SetDisabledStyle(ControlCollection controlCollection)

{

foreach(Control control in controlCollection)

{

if ( control is RadInputControl )

{

RadInputControl input = (RadInputControl)control;

input.DisabledStyle.BackColor = System.Drawing.Color.White;

input.DisabledStyle.ForeColor = System.Drawing.Color.LightGray;

Radgrid expand/collapse rows option

Hi,
I using VS2012. I am using a telerik radgrid and binding the grid to customer information in a dataset(single dataset). A single customer can have many records in the dataset. Hence in my grid i want to have my first column as a expand-collapse button '(+)' column. If a single customer is getting repeated in the dataset (which i get to know from the 'customer name' column and thier unique 'customer ID' column in the dataset), i want to display the (+) expand button, on click of expand i want to display the other records for this same customer, and on clicking collapse(-) button i want to show only one record for that customer. If the customer name is unique in the dataset then i dont want to display the expand-collapse button in the first column. Is there any way to do this ? Kindly help. Thanks in Advance.
