RadGrid: add new record and edit record

[Shehab]

Hi All,

How do I disable grid editing if I am adding a new record and how do I disable adding a new record if I am editing in the grid? only one function at a time until you click on Insert, Update, or cancle button.

Thank you in Advance,
Shehab

Hello Shehab,

One suggestion for your case would be to disable the InsertButton when in EditMode and disable the EditButtons when in InsertMode. Try out the code below for the same.

cs:

  protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
      if (e.Item.IsInEditMode)
          {
           foreach (GridCommandItem cmditm in RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem))
            {
                Button btn1 = (Button)cmditm.FindControl("AddNewRecordButton");
                btn1.Enabled = false;
                //To disable the LinkButton
                LinkButton lnkbtn1 = (LinkButton)cmditm.FindControl("InitInsertButton");
                lnkbtn1.Enabled = false;
            }

          }

     if (e.Item.OwnerTableView.IsItemInserted)
         {
           foreach (GridDataItem dat in RadGrid1.MasterTableView.Items)
             {
                   LinkButton edit = (LinkButton)dat["EditCol"].Controls[0];
                   edit.Enabled = false;
             }
           }
    }

Thanks
Princy.

Princy I have some questions with your code example...

1. From what I can tell, the grid is editMode (e.Item.IsInEditMode) regardless of whether its editing of an existing row or adding a new one. When I implemented your example, my insert button was not enabled, regardless of whether I clicked insert or edit.

2. Regarding your 2nd code block, how does that work with when I don't have an editcolumn but instead I'm using FormTemplate?


thanks,
Stewart

hi shehab,

if your UI could be a toolbar or buttons under the command item template, then you could control all of these accordingly via the radgrid's current mode flags. lots of examples on the live demo.

Hello Stewart,

1.If you want to enable the AddNewRecord button in the Insert mode and disable it in the Edit mode, you can try out the following code.
cs:

 protected void RadGrid4_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item.IsInEditMode) && (!e.Item.OwnerTableView.IsItemInserted))
          {
            foreach (GridCommandItem cmditm in RadGrid4.MasterTableView.GetItems(GridItemType.CommandItem))
            {
                Button btn1 = (Button)cmditm.FindControl("AddNewRecordButton");
                btn1.Enabled = false;
                LinkButton lnkbtn1 = (LinkButton)cmditm.FindControl("InitInsertButton");
                lnkbtn1.Enabled = false;
             }
          }

           if (e.Item.OwnerTableView.IsItemInserted)
           {
               foreach (GridDataItem dat in RadGrid4.MasterTableView.Items)
               {
                   LinkButton edit = (LinkButton)dat["Edit"].Controls[0];
                   edit.Enabled = false;
               }
           }
   }

2.The provided code should work if you have an EditCommandColumn only.

Hi Princy,

Thanks for all the help. I still have a problem with this code; it works fine when I am adding a new row in the Insert Button click because I define the edit button and disable it like this:

Dim edit As LinkButton = DirectCast(dat("EditCommandColumn1").Controls(0), LinkButton)
                edit.Enabled = False

However; when I am in edit mode it will error out Object not set to an instant of an object, I think because it can't find the control to assign it to a button and disable it and I honestly not sure what the name of the controler should be changed to here is the line where it errors out when I click on Edit to disable the Insert Button;

Dim btn1 As Button = DirectCast(cmditm.FindControl("AddNewRecordButton"), Button)
                btn1.Enabled = False
                Dim lnkbtn1 As LinkButton = DirectCast(cmditm.FindControl("InitInsertButton"), LinkButton)
                lnkbtn1.Enabled = False

Thank you again for all your help,
Shehab

Hi Yavor,

Thank you very much for your help. I tried the project and I saw it hides the Add New button when editing and then it won't show it again until page post back and same thing in Adding new item; it hides the edit from everywhere else on the page. I just want to be able to enable and disable the buttons not hide it until the page is refreshed. Thanks again.

Hello,

This works for me, but I still need to disable the + sign gif that acts as a link to add a new record also. Any ideas?

[Sebastian]

Hi Jeff,

You can disable or completely remove the [Add new record] button by defining your own command item template. Review the following article from the online documentation for more details:

Hello..
I have an problem in Add new record button. I hide this button by coding on PreRender Event of rad grid..but the + sign is still shown..i want to remove that..and i also set AddNewRecordText="". In command item setting of radgrid, i only want refresh button..neither a add new record text nor a + sign. Please help me.

[Princy]

Hi kalpna,

Can you be more specific what you are exactly trying to acquire?If you want to hide the AddNewRecord button simple set it to false on CommandItemSettings as shown below.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" >
    <MasterTableView CommandItemDisplay="Top">
      <CommandItemSettings ShowAddNewRecordButton="false" />
    </MasterTableView>
. . . . . . . . . . .
</telerik:RadGrid>

Or you can set the CSS property of the "+" sign as below,if you want to hide only that symbol.

CSS:

<style type="text/css">
    .RadGrid .rgAdd
    {
        visibility: hidden;
    }
</style>

Thanks,
Princy
