[Solved] Allow Insert, but not Edit on certain columns

[Julia Shah]

Hi,

I have a grid with one GridDropDownColumn and two GridBoundColumns. I've set AllowAutomaticInserts and AllowAutomaticUpdates to True. I add rows by selecting a value from a dropdown and entering values in the textboxes. Now I'd like to be able to edit rows by changing the values in the textboxes, but I don't want to allow editing the first dropdown column. If I put ReadOnly, then I can't use the dropdown on Insert. Is there a way to be able to insert, but not edit a column?

Thanks,
Julia

HI Julia,

Try the following code snippet to achieve the desired scenario.

CS:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item is GridEditFormItem) && (e.Item.IsInEditMode)&&(!e.Item.OwnerTableView.IsItemInserted))
        {
            GridEditableItem editItem = (GridEditableItem)e.Item;
            editItem["columnUniqueName"].Parent.Visible = false;

        }

    }

Thanks
Shinu

Thank you for your reply! I had to modify the code a little bit to make it work:

        protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode) && (!e.Item.OwnerTableView.IsItemInserted))
            {
                GridEditableItem editItem = (GridEditableItem)e.Item;
                editItem["columnUniqueName"].Enabled = false;
            }
        }

Now it doesn't let me change the selection in the dropdown, which is great. But it creates another problem: after I click on "Update" icon, the row stays in editable mode. Why is that?

Hi Julia,

Have you set AllowAutomaticUpdates to true ? If you are performing Update operation manually can you try setting AllowAutomaticUpdates to false and see whether the  Edit form is getting closed after the Update operation.

Yes, I've set AllowAutomaticUpdates to True, and I don't do the update manually in this case.

When I am in debugger, I see that this condition 

 

 

if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode) && (!e.Item.OwnerTableView.IsItemInserted))

is met even after I click on "Update".

How can I make sure that it works only on clicking "Edit", but not "Update"?

Thanks,
Julia

Hello Julia,

I'm unable to reproduce the aforementioned case. My test project is attached to this post. Could you please modify it (and send it back via support ticket) to help me recreate your scenario?
