WebGrid, Java Script Error when adding a new line on Empty Grid with 0 lines

Hello,

Yes, I understand about your point. Even though it runs well in non client binding scenario, but we suggest the same way. Otherwise, some issues can be occured due this settings. I will let us our developer know about this javascript error.

Thanks for your reply.

I already did this work around. But I still see this as a fatal bug, this behaviour is not the same with non client binding mode.

Its also not documented any where that we need to do that only on with the client side bidning!!

Hello Maged,

I am sorry that I was not being detail in my previous post. You can change the DataKeyField with ItemID, but you also need to add ItemID in your column. This the one that caused the error.
If you don't like to show ItemID column, you can set Visible false properties in that column.
When you specify a datakeyfield, It must be need also added into your column. Otherwise, you will face the error.

Handy

I think you didn't get my point here.

In your sample you have <ISWebGrid:WebGridColumn> for FirstName. Try to remove that Column from the grid, and your sample will not work as well. KEEP the DataKeyFielda as it is.

Add on your database ItemID , then make it as your DataKeyField but do NOT add it as <ISWebGrid:WebGridColumn> at all

On your sample, you can replace ClientBindingWebService.aspx code with the next code in order to replicate the issue easier:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ClientBindingWebService.aspx.cs"
    Inherits="ClientBindingWebService" %>

<%@ Register Assembly="ISNet.WebUI.WebGrid" Namespace="ISNet.WebUI.WebGrid" TagPrefix="ISWebGrid" %>

    <script type="text/javascript">
        function MyInfo()
        {
            this.FirstName = "";
            this.LastName = "";
            this.Age = "";
        }
    
    </script>
</head>

                    <ISWebGrid:WebGridColumn Caption="Last Name" DataMember="LastName" Name="LastName"

Hello Maged,

Based on Martin sample, there is no field "ItemID" in his database. Also, DataKeyField is necessary to be filled. Otherwise, you will find some issue in insert, update and delete. Please fill DataKeyField properties with your current Primary key in database.

Handy

Hi,

With futher inverstigation, I think you still have the issue not fixed. And here is the root cause:

In your sample, you have this definition:

<ISWebGrid:WebGridColumn Caption="First Name" DataMember="FirstName" Name="FirstName"

Width="100px">

</ISWebGrid:WebGridColumn>

Ok, try to make small change on your sample, and the problem will apear right a way:

<ISWebGrid:WebGridColumn Caption="First Name" DataMember="FirstName" Name="FirstName"

Width="100px">

</ISWebGrid:WebGridColumn>

Now, on your WebGrid_ClientBinding.js , you have this code:

vbaa90.KeyValue =v18b39.Cells.GetNamedItem(vc2f92.DataKeyFields).Value;

This code will only work if you have at least one cell defined with the same name as the DataKeyField.

Again, on your sample if you just removed the first column (firstname), you will have the same issue I have.

Please, if you can send me the fix ASAP that will be great.

Thanks,

Maged

Hello,

I have attached a recorded video showing how the project works on my end using the latest version 7.0.7200.418.

I have uploaded the project sample along with its assemblies file. You can download the link here.

Just let me know whether the project works fine on your end.

Thank you.

Hello Maged,

Did you apply the assemblies in your project's bin folder?

Update Manager will only update the assemblies in [Installation Folder]\Intersoft Solutions\WebUI Studio for ASP.NET. Means that you need to apply manually on your project's bin folder.

Here is the step to update WebGrid build version:

Open WebGrid's bin directory from [Installation Folder]\Intersoft Solutions\WebUI Studio for ASP.NET\WebGrid.NET 7.0\Bin.
Copy ISNet.WebUI.WebGrid.dll, ISNet.WebUI.WebGrid.Resources.dl, ISNet.WebUI.WebGrid.ISChartEngine.dll and paste it into your project's bin directory.
Delete ISNet.WebUI.WebGrid.Editor.dll from GAC (located in C:\Windows\assembly).
Drag ISNet.WebUI.WebGrid.Editor.dll from [Installation Folder]\Intersoft Solutions\WebUI Studio for ASP.NET\WebGrid.NET 7.0\Bin to GAC.

You might want to update WebUI Framework build version too:

Open WebUI Framwork's bin directory from [Installation Folder]\Intersoft Solutions\WebUI Studio for ASP.NET\WebUI.NET Framework 3.0\Bin.
Copy ISNet.WebUI.Resources.dll and paste it to your project's bin directory.
Delete ISNet.dll, ISNet.WebUI.dll, ISNet.WebUI.Design.dll, ISNet.WebUI.Editor.v4.dll and ISNet.WebUI.Silverlight.dll from GAC (located in C:\Windows\assembly).
Drag ISNet.dll, ISNet.WebUI.dll, ISNet.WebUI.Design.dll, ISNet.WebUI.Editor.v4.dll and ISNet.WebUI.Silverlight.dll from [Installation Folder]\Intersoft Solutions\WebUI Studio for ASP.NET\WebUI.NET Framework 3.0\Bin to GAC.

To ensure that you have used the latest build version, right-click on WebGrid control when you are in Design view on your project and select About. It will show a dialog box that contains information about WebGrid and WebUI Framework build version you are currently using.

Hope this helps.

Thank you.

The update manager shows nothing to update stating that I'm up to date!

I uninstalled and reinstalled, and rerun update manager several times, and still getting the same result!
Is there any kind of cashing somewhere? Or how can I make sure that when I run my project, I have the latest version and assemblies on my bin directory?
What do you mean update WebUI Framework?

Thanks,
Maged

Hi Guys,

I've a WebGrid, using client binding and WebService as DataSource type.

When I've the grid empty with 0 lines, and try to insert a new line, it always give me a Java script error and the grid stops responding after that and the new line doesn't show up , but in the second time if we have at least one line it works ok.

Please let me know how can we fix that?

Thanks,

Maged
