Hi,

In my current project, I have a RadGrid with multilevel grouping which contains editable checkboxes.

However, it is not possible to collapse the group of items in the RadGrid.

The code is given below and the webpage is available on http://www.gouw.ws/EditGrouping.aspx

Can you please tell me how to make the RadGrid collapsible?

ASPX:
=====
<telerik:RadGrid ID="RadGrid1" AutoGenerateColumns="false" AllowMultiRowEdit="true"
    OnNeedDataSource="RadGrid1_NeedDataSource" OnPreRender="RadGrid1_PreRender" runat="server">
    <ClientSettings EnableAlternatingItems="false">
        <Scrolling UseStaticHeaders="true" />
    </ClientSettings>
    <MasterTableView EditMode="InPlace" TableLayout="Fixed">
        <GroupByExpressions>
            <telerik:GridGroupByExpression>
                <GroupByFields>
                    <telerik:GridGroupByField FieldName="Category" SortOrder="Ascending" />
                </GroupByFields>
                <SelectFields>
                    <telerik:GridGroupByField FieldName="Category" HeaderText="Category" />
                </SelectFields>
            </telerik:GridGroupByExpression>
            <telerik:GridGroupByExpression>
                <GroupByFields>
                    <telerik:GridGroupByField FieldName="Type" SortOrder="Ascending" />
                </GroupByFields>
                <SelectFields>
                    <telerik:GridGroupByField FieldName="Type" HeaderText="Type" />
                </SelectFields>
            </telerik:GridGroupByExpression>
        </GroupByExpressions>
        <Columns>
            <telerik:GridBoundColumn DataField="Name" DataType="System.String" HeaderText="Name" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" ReadOnly="true" UniqueName="Name" />
            <telerik:GridCheckBoxColumn DataField="Email" DataType="System.Boolean" HeaderText="Email" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" ReadOnly="false" UniqueName="Email" />
            <telerik:GridCheckBoxColumn DataField="SMS" DataType="System.Boolean" HeaderText="SMS" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" ReadOnly="false" UniqueName="SMS" />
            <telerik:GridCheckBoxColumn DataField="NotifyByEmail" DataType="System.Boolean" HeaderText="Notify By Email" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" ReadOnly="false" UniqueName="NotifyByEmail" />
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

ASPX.CS:
========
public partial class EditGrouping : System.Web.UI.Page
{
    private List<Data> _data = null;
 
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            _data = Data.Load();
            Session["DATA"] = _data;
        }
        else
        {
            _data = (List<Data>)Session["DATA"];
        }
    }
 
    protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
    {
        this.RadGrid1.DataSource = _data; ;
    }
 
    protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem item in this.RadGrid1.Items)
        {
            item.Edit = true;
        }
        this.RadGrid1.Rebind();
    }

Hello Herman,

The problem is because of rebinding the grid in PreRender event. You can put grid items in edit mode without additionally rebinding the grid by using EditIndexes collection before grid is bound. Try the following code in PageLoad event.

C#:
protected void Page_Load(object sender, EventArgs e)
    {
        for (int i = 0; i < RadGrid1.PageSize; i++)
        {
            RadGrid1.EditIndexes.Add(i);
        }
    }

Also please take a look at the following documentation
Put all items in edit mode without additional rebind

Thanks,
Princy.

Hi Princy,

Thanks a lot for your prompt and quick reply.

I have tried your solution during the weekend.

I found out that only the first 10 lines of the gird are editable.

Here is the screen shot ... Edit Grouping Screen Shoot

Below are the source code.

Herman

Hello Herman,

Since you have not enabled Paging, instead of using 'RadGrid1.PageSize' iterate through using "_data.Count" (after populating the List) as shown here.

C#:
  for (int i = 0; i <_data.Count; i++)
     {
         RadGrid1.EditIndexes.Add(i);
     }

Hope this helps,
Princy.

Hi Princy,

I need to add an editable checkbox field on each Type grouping header as shown on Edit Grouping Screen Shot

The value will be initialised from the data object and the new value will be saved into the data object when the user press the Save button.

I need to do this on server side.

Can you please show me how to do this?

Regards,
Herman

Hi Princy,

The web page in my project is very similar to http://www.gouw.ws/EditGrouping.aspx

When the user clicks on the Save button, the data object will be sent to the back-end (and saved).

The user requested to add an editable check box in the Type Grouping Header as shown on http://www.gouw.ws/EditGrouping.jpg

When the user clicks on the check box, the value will be updated into the data object.

Is it possible to add an editable check box in the Type Grouping Header?

If it is, can you please give a sample on how to do this?

The code of the above web page are as follows:

Hi Herman,

In order to achieve the desired functionality, you can use the logic from that CodeLibrary article. As the sample project there uses an old version of RadControls, I am attaching an updated sample to this post for you to view.

Anyway, keep in mind that a limitation in this implementation is the fact that group header items text is lost during the process of adding the checkbox. I hope that this will not be a problem in your scenario.

All the best,

Thanks Tsvetina.

I have done more investigations and it looks like the suitable solution for my project will be hierarchy model instead of grouping model of RadGrid. I am now reading more samples and demos about this model and will try it out.

Hi Tsvetina,

I have converted this RadGrid from Grouping model into Hierarchy model.

The new web page is available on http://www.gouw.ws/HierarchyWithDS.aspx

However, I am having difficulty in trying to set every row or the RadGrid with editable checkboxes to edit mode similar to the Grouping model on http://www.gouw.ws/EditGrouping.aspx

For details description of the problem, please check the following thread http://www.telerik.com/community/forums/aspnet-ajax/grid/how-to-put-the-grid-items-of-a-hierarchy-model-radgrid-in-edit-mode.aspx

Can you please help me?

Hi Herman,

I am not sure that I understand you correctly, as there is some problem with loading the links that you posted and I cannot see how the grouped RadGrid looks in the sample page. Also, is the problem which you are encountering with putting the rows into edit mode or is it with implementing the checkboxes themselves.?

Could you please post a screenshot of how you want your grid to look with all your requirements listed, so we can offer you a more straight-to-the-point solution.

Thank you in advance.

I have exactly the same problem but the solution you gave does not help when I go to a different page grid. When I go to another page I get the lines do not edit. Can you help me with this?

Hello Nissim,

Can you paste the code you use that causes the problematic results? There were a few suggestions made here and I am not sure which one exactly you have in mind. If you are talking about putting all items in edit mode, you can also try the other suggestions in the previously linked help article:

Hi Nissim,

You could then try one of the other two approaches.

If you use EditForms edit mode:
protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (!Page.IsPostBack && e.Item is GridEditableItem)
    {
        e.Item.Edit = true;
    }
}

If you use InPlace, you can try the following approach, however keep an eye on performance, as it requires a second rebind of the grid control:
protected void RadGrid1_PreRender(object sender, System.EventArgs e)
{
    if (!IsPostBack)
    {
        foreach (GridItem item in RadGrid1.MasterTableView.Items)
        {
            if (item is GridEditableItem)
            {
                GridEditableItem editableItem = item as GridDataItem;
                editableItem.Edit = true;
            }
        }
        RadGrid1.Rebind();
    }
}

Thank you,
Now I see another problem - when I drag the column to grroup , it's O.K,
but after collapse or group the datasource is null and I cannot use rebind .
What can I do?
Thanks.

Hi Nissim,

Doesn't the NeedDataSource event fire on (un)grouping your grid? If it does not, please review your code for any calls to DataBind() or DataSource settings unfollowed by Rebind() call.
Also, if your grid is not too great in terms of records, you could try using GroupLoadMode="Client" and see if the problem remains.
If you want us to help you straight away, you could open up a formal support ticket and send a small runnable sample demonstrating the problem that you have encountered. We will debug it and let you know how it can be fixed.
