Hello,

I have an ajaxified rad grid with a column that holds a delete button. When the button is clicked, i rebind the grid to the datasource and then I disable some checkboxes.

When this happens, these checkboxes are not disabled.

Here is my grid:

<telerik:RadGrid ID="dgLoginRequest"

runat="server"

AllowSorting="True"

AllowPaging="True"

AllowAutomaticUpdates="True"

Skin="WebBlue"

EnableAJAX="true"

EnableOutsideScripts="true"

GridLines="None"

GroupingSettings-GroupContinuesFormatString=""

OnPageIndexChanged="dgLoginRequest_PageIndexChanged"

OnItemDataBound="dgLoginRequest_ItemDataBound"

OnNeedDataSource="dgLoginRequest_NeedDataSource">

<ClientSettings>

<Selecting CellSelectionMode="None" AllowRowSelect="False" />

</ClientSettings>

<MasterTableView AllowAutomaticDeletes="True"

AllowAutomaticUpdates="True"

AutoGenerateColumns="False"

CommandItemDisplay="None"

DataKeyNames="EntityID"

Width="100%">

<CommandItemSettings ExportToPdfText="Export to PDF" />

<RowIndicatorColumn>

<HeaderStyle Width="20px" />

</RowIndicatorColumn>

<ExpandCollapseColumn>

<HeaderStyle Width="20px" />

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn DataField="EntityID" HeaderStyle-HorizontalAlign="Center" HeaderText="Entity ID" ItemStyle-HorizontalAlign="Left" SortExpression="EntityID" Visible="False" UniqueName="EntityID">

<HeaderStyle HorizontalAlign="Center" />

<ItemStyle HorizontalAlign="Left" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="EntityName" HeaderText="Entity Name" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Left" SortExpression="EntityName" UniqueName="EntityName">

<HeaderStyle HorizontalAlign="Center" />

<ItemStyle HorizontalAlign="Left" />

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderStyle-HorizontalAlign="Center">

<HeaderTemplate>

<asp:CheckBox id="headerReaderChkbox" runat="server" Text="Reader"></asp:CheckBox>

</HeaderTemplate>

<ItemTemplate>

<asp:CheckBox ID="chbxReader" runat="server" Checked='<%# Eval("IsReader") %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderStyle-HorizontalAlign="Center">

<HeaderTemplate>

<asp:CheckBox id="headerDropboxChkbox" runat="server" Text="RK Dropbox"></asp:CheckBox>

</HeaderTemplate>

<itemtemplate>

<asp:CheckBox ID="chbxRKDropbox" runat="server" Checked='<%# Eval("IsRKDropbox") %>' />

</itemtemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText=" ">

<ItemTemplate>

<asp:ImageButton ID="btnDelete"

runat="server"

CausesValidation="False"

ImageUrl="../Login/Images/Delete.gif"

ToolTip="Delete Record"

OnClick="btnDelete_Click"/>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

<GroupByExpressions>

<telerik:GridGroupByExpression>

<GroupByFields>

<telerik:GridGroupByField FieldName="FamilyName" />

</GroupByFields>

<SelectFields>

<telerik:GridGroupByField FieldName="FamilyName" FieldAlias="FamilyName" HeaderText="FamilyName" />

</SelectFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableTheming="True" Skin="WebBlue">

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

</FilterMenu>

</telerik:RadGrid>

Here is my delete click

protected void btnDelete_Click(object sender, EventArgs e)

{ 

                var
 
 
 dataItem = (sender as ImageButton).NamingContainer as GridDataItem;
 
 
 
 
                foreach (EntityUserRole item in DataSource)
 
 
 
                    if (int.Parse(dataItem.GetDataKeyValue("EntityID").ToString()) == item.EntityID)
 
                    {
                        DataSource.Remove(item);
                        BindDataGrid();
 
 
                        break;
 
                    }

foreach (GridDataItem row in dgLoginRequest.MasterTableView.Items)

{

var entityID = (int) row.GetDataKeyValue("EntityID");

var chbxReader = (CheckBox) row.FindControl("chbxReader");

var chbxRKDropbox = (CheckBox) row.FindControl("chbxRKDropbox");

var chbxPrivateReader = (CheckBox) row.FindControl("chbxPrivateReader");

var chbxShare = (CheckBox) row.FindControl("chbxShare");

chbxReader.Enabled = false;

chbxRKDropbox.Enabled = false;

}

}



 
 
public void BindDataGrid()
 
{
    dgLoginRequest.DataSource = DataSource;
    dgLoginRequest.DataBind();
}

Why aren't these checkboxes being disabled?
