Is it feasible to have a RadGrid that basically always has every row in edit/insert mode at all times, in essence removing the need of a method of selecting a row for editing?  If so, is there a demo that demonstrates this?

Thanks,
Aaron

There are a few ways to do this. Either you use the following piece of code:

protected void MyGrid_ItemCreated(object sender, GridItemEventArgs e) 
    { 
        if (e.Item is GridEditableItem) 
        { 
            (e.Item as GridEditableItem).Edit = true
        } 
    } 
 

Which sets up the items to be editable through the ItemCreated event, or you do the following:
   protected void Page_Load(object  sender, EventArgs e) 
   { 
        for (int i = 0; i < RadGrid1.PageSize; i++) 
       { 
           RadGrid1.EditIndexes.Add(i); 
       } 
   } 

Which sets it up in the PreRender event.

Hi Abonfig,

You can also refer to the following help document which demonstrtaes on how to force the grid items in edit mode when the grid displays initially on the page:
Default edit mode for grid items on initial load

Happy New Year!

Hello,

Thanks for the suggestions.  The "ItemCreated" method, while it runs without errors, does not seem to do anything.  The grid rows do not appear in "edit" mode.

Using the "Default edit mode for grid items on initial load" method, I get an error when I try to run the grid's rebind event:
Specified argument was out of the range of valid values.
Parameter name: index


Any thoughts as to what could be happening here?

Thanks,
Aaron

Additional information:  it looks like the rows are being "selected" as if I am clicking on them, but they are still read-only and I am expecting to see the columns with textboxes, checkboxes, etc.  Perhaps I am missing a configuration setting?

Thanks,
Aaron

Just to make sure: have you defined an edit form or an in-line edit form for which to use for the editing? This is what is displayed when a row is in edit-mode, and it would fall under the configuration area!

I am currently setup for "InPlace" editing.

Just to clarify, are you saying I need to do some additional setup in the grid's configuration when using InPlace editing?  I've used InPlace edit mode in other grids and have never had to declare any kind of "in-line edit form".  Is there documentation/examples on this?

Also don't know if it makes a difference but I am using the NeedDataSource event to populate the grid.

Thanks,
Aaron

Hello Aaron,

Attached to this post you will find a sample which has a RadGrid (connected to a SqlDataSource) which has in-place editing and all its rows are in edit-mode when the page is loaded. Something to note is that you have to set the AllowMultiRowEdit property to true otherwise you cannot have several rows editable at once. Take note that the example uses the PreRender approach discussed in the previously linked documentation article.

Best wishes,
Carl

Edit: Carl beat me to it!

Anyways, I don't think that the NeedDataSource event should make a difference, since these events are all fired no matter what way the data is bound.

Carl - Thanks, but I did try that method, and as I mentioned in a previous post I got the following error on the line of code that calls the Rebind() method:
Specified argument was out of the range of valid values.
Parameter name: index


I have ensured that I have AllowMultiRowEdit property set to true.  One interesting thing I noticed...if I declare an <EditItemTemplate> markup in the grid declaration with a background color of red, when the page renders, each row in the grid has a thin red line underneath it.  This seems to tell me that it is partially working, but I am missing something to get the textboxes to appear for in-line editing.

If it helps, here is the grid code:

<telerik:RadGrid ID="rgInvoiceCharges" runat="server"   
            Width="700px" AllowMultiRowEdit="true" AutoGenerateColumns="false" 
            OnNeedDataSource="rgInvoiceCharges_NeedDataSource"

            OnPreRender="rgInvoiceCharges_PreRender" >  
            <MasterTableView CommandItemDisplay="Top" AutoGenerateColumns="false" EditMode="InPlace" ShowFooter="true">  
                <NoRecordsTemplate></NoRecordsTemplate>  
                <CommandItemTemplate></CommandItemTemplate>  
                <FooterStyle HorizontalAlign="left" />  
                <Columns>  
                      
                    <telerik:GridBoundColumn UniqueName="GridKey" DataField="GridKey" HeaderText="Grid Key" Visible="False">

Hello Aaron,

I tested your Grid setup and was unable to reproduce the error you were receiving. I managed to get a Grid with all rows already in edit mode.

Would you be able to package your implementation into a working sample (which displays the issue) and submit it in a support ticket?

Sincerely yours,
Carl

I got the demo working and made a few changes to suit my particular needs but how do I get the fields in all rows to stay editable when grid paging is on? They revert back to the default behaviour when I move to another page.

Hi,

You can set all the rows to always be in edit in the PreRender event  as shown below:

C#
  protected void RadGrid1_PreRender(object sender, EventArgs e) 
    { 
            foreach (GridDataItem dataItem in RadGrid1.Items) 
            { 
                dataItem.Edit = true
            } 
            RadGrid1.Rebind(); 
    } 


Hope this helps.

Thanks

Hi Princy,
I'm following your example and also your tutorial
http://www.telerik.com/help/aspnet-ajax/grid-put-all-items-in-edit-mode-no-additional-rebind.html
but is not working.
As you can see from the screenshot only the last record is in editmode

<telerik:RadGrid runat="server" ID="Grid1" OnPreRender="Grid_PreRender" OnNeedDataSource="NeedDataSource">
    <MasterTableView AutoGenerateColumns="false" EditMode="InPlace" CommandItemDisplay="Top"
         DataKeyNames="Spnid"
         ShowGroupFooter="true" >
         <Columns>
              
             <telerik:GridBoundColumn DataField="Spncod" HeaderText="Codice" UniqueName="Spncod">
             </telerik:GridBoundColumn>
             <telerik:GridBoundColumn DataField="TipoSoglia" HeaderText="Tipo Soglia" UniqueName="TipoSoglia">
             </telerik:GridBoundColumn>
             <telerik:GridBoundColumn DataField="Count" HeaderText="Conteggio" UniqueName="Count" FooterText="Sum Count : " Aggregate="Sum">
             </telerik:GridBoundColumn>
               <telerik:GridCalculatedColumn HeaderText="Count+Count*3" UniqueName="Count3" DataType="System.Double"
                 DataFields="Count, Count" Expression="{0}+{1}*3" FooterText="Count+Count*3 : "
                 Aggregate="Sum">
             </telerik:GridCalculatedColumn>
             <telerik:GridButtonColumn ConfirmText="Delete it?" ConfirmDialogType="RadWindow"
                 ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" Text="Delete"
                 UniqueName="DeleteColumn">
                 <ItemStyle HorizontalAlign="Center" CssClass="MyImageButton"></ItemStyle>
             </telerik:GridButtonColumn>
         </Columns>       
     </MasterTableView>
  
 </telerik:RadGrid>


protected void Page_Load(object sender, EventArgs e)
    {
        
         
    }
 
    protected void NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        List<MyList> dataList1 = Data1.LoadData();
        Grid1.DataSource = dataList1;
    }
 
 
 
    protected void Grid_PreRender(object sender, System.EventArgs e)
    {
        foreach (GridDataItem dataItem in Grid1.Items)
        {
            dataItem.Edit = true;
        }
       Grid1.Rebind();
    }

I'm using the last version of telerik

Thanks

Hello Stefania,

You need to specify that multi row editing will be allowed in your RadGrid by setting the AllowMultiRowEdit property to true:
<telerik:RadGrid runat="server" ID="RadGrid1" AllowMultiRowEdit="true">
    <MasterTableView>

Please give this a try and see if you get the desired behavior after applying that change.

Hi, I am looking for this but instead of the datasource being a database, I want to update a data table.

Thanks!

Hi,

There is no built-in functionality that could allow you to update a DataTable object. The only thing that I could suggest for such requirement is that you save your DataTable object to the Session and modify it manually by traversing through each item of the grid and retrieving the new values. Then, within the OnNeedDataSource event of the grid you could pass the DataTable from the Sessions.

Hope this helps.
