[Solved] How do I set a default value with Client Edit: Add

[Frank Michael]

I am using a Grid with Ajax Binding and Client Edit.
When I insert a new record, I want to set a default value for a field. How can I do that, because there is no controller request.

[Frank Michael]

Can you quickly tell my if my requirement is out of scope or in scope of Telerik Grid?

[Frank Michael]

I think I should be able to do this with jQuery

[Frank Michael]

I wasn't able to do it. I am only a jQuery beginner and I can not invest too much time into it.
I suggest a Helper Function:

c.Bound(r => r.RemainingHours).InsertDefaultValue(1);

This question is still open.
I have applied for support tickets, but it is not yet active. So any help in the meanwhile is appreciated.

You wrote:
"If you want to set default value for a grid editor you must provide an editor template for that column which contains some control with default value set. You may have to write some JavaScript in order to set the default value only if required."

If I have two problems with your proposal:
1) Number.ascx is defined as:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<double>" %>

<%= Html.Telerik().NumericTextBox()
        .Name(ViewData.TemplateInfo.HtmlFieldPrefix)
        .Value(Model)
%>

If I write this:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<double>" %>

<%= Html.Telerik().NumericTextBox()
        .Name(ViewData.TemplateInfo.HtmlFieldPrefix)
        .Value(1)
%>

Then I have the problem that I have 1 as default value for all Numbers, which I do not want. I have two fields: RemainingHours and RemainingDays. I only want the default value in RemainingHours, not RemainingDays.

2.
If I define a new View RemainingHours.ascx containing the default value, I have to create so many templates for different fields and default values, although I would want them only for different types. At least, yes, this is a workaround. But I think in the future there should be a more elegant way.

[Frank Michael]

And there is another problem with 2:
The default value is then used always: even when editing and even if there already was another value. This does not work. So the approach 2. does not work as well.

Hello Frank Michael ,

Yes. That's why I wrote this "You may have to write some JavaScript in order to set the default value only if required.". You need to add a script block and set the value through JavaScript if such a value is not set.

But what does "value not set" mean, if it is a double type?

Just if value == 0 is not the answer, because it may be 0 intentionally.

So my problem is how do I transport the information from outside into the EditorTemplate, that the or a default value should be set?

Or, if I write the javascript not in the template, but in the view, then I have to distinguish if the form line is a create case or an update case.

Theoretically I might catch the add.. button click event. Is that the way to go?

Hi Frank Michael ,

If you want to set default value use the UIHint to specify the editor for the particular type. Or capture the click event of the add/edit button, then find the required html element and set its value to whatever you want. If you choose that you need to use setTimeout in order for the editing UI to be created.
