CheckedChanged event not firing in dynamically created GridCheckBoxColumn

[rajesh]

Hi,

I am programatically creating few GridCheckBoxColumn in the grid and in the ItemCreated event of the grid i am adding the CheckedChanged event but the CheckedChanged event is not getting fired.

Can you please help me to fix this.

ASPX:

<ic:SettingGrid runat="server" ID="grRemainderMappings" DisableAddNew="true" OnItemCreated="grRemainderMapping_ItemCreated">
                                <MasterTableView>
                                    <Columns>
                                            <telerik:GridBoundColumn UniqueName="AppointmentReasonId" DataField="AppointmentReasonId" HeaderText="AppointmentReasonId" Display="false"/>
                                            <telerik:GridBoundColumn UniqueName="ReasonCode" DataField="ReasonCode" HeaderText="Reason Code"/>
                                            <telerik:GridBoundColumn UniqueName="Description" DataField="Description" HeaderText="Description"/>
                                        </Columns>
                                        <NoRecordsTemplate>
                                                <div class="ListGridNoRecords">There are no selected templates to display</div>
                                        </NoRecordsTemplate>
                                    </MasterTableView>
                                </ic:SettingGrid>

C#:

protected void grRemainderMapping_ItemCreated(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)

                        }
                        checkBoxColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Center;
                    }
                }
            }
            catch (Exception ex)

            }
            return dtMapping;
        }

 protected void Page_Load(object sender, EventArgs e)
        {
            try
            {
                if (!this.IsPostBack)
                {
                    grRemainderTemplates.DataSource = loadTemplatesGrid();
                    grRemainderTemplates.DataBind();

            catch (Exception ex)

            }
        }

Thanks in advance.

Hi,

Try attaching the event using the RadGrid ItemDataBound event and see how it goes.

Hi,

Can you please check if any javascript error appear on the page when you are using the chekbox control? Also if any Ajax settings exists on the page, remove them and see how it goes.

Hi Maria,

It started working after setting enableviewstate=false in the grid.

Thankyou.
