Grid control inside update panel not triggering button click event

KK Karthick Kuppusamy Syncfusion Team November 23, 2016 11:06 AM UTC

Hi Abhishek,

We have analyzed your requirement and we are able to reproduce the reported issue at our end while binding the large data to the grid.So we suggest you to use the URL Adaptor to bind the huge amount of data.

For you convenience we have created the sample that can be downloaded from the below link.

Link: https://www.syncfusion.com/downloads/support/forum/126956/ze/WebSite31896520200

In this sample we have achieved your requirements on button click by passing the URL in the client side of button click and prevented the server side button events. We have passed the URL in the dataSource method of grid using ej.DataManager.

Now the data will be bound to grid when clicking the button.

Please refer the below code example.

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">

<asp:Button ID="btnProcess" runat="server" Text="Read the Data to server"OnClientClick="return Navigate();" OnClick="btnProcessStrategy_Click"UseSubmitBehavior="false" />

<ej:Grid ID="Grid" runat="server" AllowPaging="True">

…

</ej:Grid>

</ContentTemplate>

</asp:UpdatePanel>

function Navigate() {

var obj = $('#<%= Grid.ClientID %>').data("ejGrid");

$("#autoComp").val((selectedvalue));

obj.dataSource(ej.DataManager({ url: "Default.aspx/DataSource", adaptor: newej.UrlAdaptor() }));

}

</script>

</asp:Content>

Also please refer the documentation link about dataSource method.

Link: https://help.syncfusion.com/api/js/ejgrid#methods:datasource

https://help.syncfusion.com/aspnet/grid/data-adaptors#url-adaptor

If we misunderstood your requirement then could you please share the following details.

1.Please share the grid code.

2.How much data binded for the grid through the button click?

3. Share the video to know in what scenario you have faced the issue.

4.Share the sample if possible or share more information to reproduce the issue.

The provided information will help us to analyze the issue and provide you the response as early as possible.

Regards,

Karthick.K.

Hi Karthick,

Thanks for quick response. But this solution does not work for me because i am using sqldatasource for databinding to grid. Now, I am sharing the complete code with you, so you can understand the problem that i am facing. Here is the code:

Hi Abhishek,

While we binding the large amount of sql data to the grid we are faced the reported issue and we suggest you to use the ‘SqlLoadOnDemand’ concept for your requirement

Online sample link: https://asp.syncfusion.com/demos/web/grid/sqlloadondemand.aspx.

K.Karthick.

Problem is not with databinding concept, if i remove the update panel from the page, grid works fine. I think there is some javascript code confliction of asp script manager with ej grid javascript files. You have to help with Javascript error. Kindly go through the code once again.

KK Karthick Kuppusamy Syncfusion Team November 29, 2016 01:50 AM UTC

Hi Abhishek,

We have analyzed your provided code and still we are not able to reproduce the reported issue.

Please find the code example.

<asp:Updatepanel ID="panel1" runat="server">

<ej:Grid ID="EmployeesGrid" runat="server" Width="900px" AllowPaging="true" AllowFiltering="true" AllowSorting="true">

<ej:Column Field="CustomerID" IsPrimaryKey="true" HeaderText="Customer ID" Width="80" />

<ej:Column Field="CompanyName" HeaderText="Company Name" Width="80" />

<ej:Column Field="ContactName" HeaderText="Contact Name" Width="100" EditType="Numeric" />

<ej:Column Field="Address" HeaderText="Address" Width="80" />

</Columns>

</ej:Grid>

<asp:SqlDataSource ID="SqlData" runat="server" ConnectionString="<%$ ConnectionStrings:SQLConnectionString %>"

SelectCommand="SELECT * FROM [Orders]"></asp:SqlDataSource>

</ContentTemplate>

</asp:Updatepanel>

$(document).ready(function () {

$("#aspnetForm").submit(function () {

alert("hi");

});

return false

</script>

</asp:Content>

Sample link: https://www.syncfusion.com/downloads/support/directtrac/general/ze/Updatepanel1354150083.zip.

If you still faced the issue could you please share the sample or modify the sample as issue reproducible.

Regards,

K.Karthick.

AS Abhishek Shandilya November 29, 2016 01:53 AM UTC

In order to re-produce the issue, you have to add asp button inside update panel and define its click event on server side.

KK Karthick Kuppusamy Syncfusion Team November 29, 2016 01:42 PM UTC

Hi Abhishek,

We have created a sample based on your requirement and we are unable to reproduce the issue.In that sample we have created a asp button and we define its click event in server side.

Please find the code example.

asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">

<asp:Updatepanel ID="panel1" runat="server">

<asp:Button OnClick="Unnamed_Click" Text="clickthecolumn" runat="server" />

<ej:Grid ID="Grid1" runat="server" DataSourceID="SqlDataSource1" MinWidth="0" AllowPaging="true">

<ej:Column AllowEditing="False" DataType="number" Field="OrderID" HeaderText="Column4" IsIdentity="True" IsPrimaryKey="True">

</ej:Column>

<ej:Column DataType="string" Field="CustomerID" HeaderText="Column4">

</ej:Column>

<ej:Column DataType="number" Field="EmployeeID" HeaderText="Column4">

</ej:Column>

<ej:Column DataType="date" Field="OrderDate" HeaderText="Column4">

</ej:Column>

</Columns>

</ej:Grid>

</ContentTemplate>

</asp:Updatepanel>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:SQLConnectionString %>" SelectCommand="SELECT [OrderID], [CustomerID], [EmployeeID], [OrderDate] FROM [Orders]"></asp:SqlDataSource>

</asp:Content>

Please find the snapshot for the serverside click event.

Sample Link: https://www.syncfusion.com/downloads/support/directtrac/general/ze/NOW-1952257705.zip.

Please share the sample or modify the sample as issue reproducible and revert back to us.
