Hello,

Sorry for replying so late b/c i wasn't able to check email.

Design: 

 What you need to do is actually really simple:  In your webgrid, create a templatedcolumn and use an asp:LinkButton

<igtbl:TemplatedColumn AllowUpdate="No" Key="TestColumn">
        <CellTemplate>
            <asp:LinkButton ID="lBtnTest" runat="server" Text="Test" OnClick="lBtnTest_Click" />
        </CellTemplate>
        <Header Caption="Test Column">
            <RowLayoutColumnInfo OriginX="9" />
        </Header>
        <Footer>
            <RowLayoutColumnInfo OriginX="9" />
        </Footer>
    </igtbl:TemplatedColumn>

 C# Code in behind:

In your C# code, you inside the linkbutton event,

protected void lBtnTest_Click(object sender, EventArgs e)
{

string sScript = null;

string sHeight  = 400px;  // or whatever size you want your modal to be

string sWidth = 400px;  // or whatever size you want your modal to be

//If you need to pass any data to the modal then do it in the line below after the sTitle variable

 sScript = "<script>var rc=new Array(0,0); rc=window.showModalDialog('Test.aspx?Title=" + sTitle + "','','dlgHeight:" + sHeight + " px;dlgWdith:" + sWidth + " px');" + "\n";

//this line of code handle the case where I want to return a value back to parent screen from the modal
            sScript += "if(rc!=null){document.getElementById('returnvaluetoparentscreen').innerText=rc[0]; __doPostBack('','');}</script>";

//This line of code register the script

            this.ClientScript.RegisterStartupScript(typeof(Page), "showModalDialog", sScript);

}

If you just take this code and follow my example, it should give / invoke the modal and whatever you need to pass to the modal, you can do it after you can get it to invoke.

 Let me know if you need futher help.

Hello Sudhakar, 

You can do it declaratively and use the CommandArgument of the link + databinding expressions to store custom values (0 to 4). They however need to be present in the datasource (each row should have a column with these values - in my case, the column in the datasource is productId

<asp:LinkButton ID="EditSaveButton" Runat="server" OnClick="EditSave_Click" CommandArgument='<%# Eval( "productId" ) %>'>(Edit)</asp:LinkButton>

Thank very much for your help,

I need one more help from you. My Link button number is Columns(2). but i need Columns(1) value when ever i click link button.

please help me.

You can probably have them separated with comma. Say, column[1] is ProductName, and columns[2] is ProductID. Example:

<asp:linkbutton CommandArgument="<%# Eval('ProductID') %>, # Eval('ProductName') %>"

Or you can use CommandName in addition to argument, example 

<asp:linkbutton CommandArgument="<%# Eval('ProductID') %>" CommandName="<%# Eval('ProductName') %>" 

Thank you for your help,

Please help me this question also:

How to bind Link button dynamic?  using the UltraWebGrid_InitializeLayout.

Sofia,

Thanks for your help.

InitializeDataSource Event not match for my requirement. any other aways possible to implement?

Hello,

I am also trying to pick up the pieces and get the whole picture right, but it is a bit difficult for me to get everything right away. For DataBinding, I would suggest a couple of things

1) If possible, always use the InitializeDataSource event of the grid to bind the grid with data - this event is automatically called when the grid needs data

2) Take a look at the following blog post - it provides internal insights how data is bound to the grid and how to use it

 Helloo,

Please help me below issues

This is the first time I am using Infragistics controls, I have searched this forum and the net but have not found a solution to my problem.

I have a search form on my .Net page, on pressing a submit I bind the UltraWebGrid(from code behind) and make the asp Panel contianing the UWG visible. One of the Columns of the UWG is a templated column containing an ASP linkbutton. OnClick of the link button is wired on the page. There is no paging on the grid.

So far so good. I get an error when I press the Link button; object reference not set...... The error points to one of the controls on the templated columns. It seems some sort of rebinding is required...something to do with viewstate.

Can some help me in figuring out what could be wrong, perhaps pointing to some code sample that does what I have described above.

Thanks for help. I have  found the solution and resolved the issues.

Code:

<igtbl:TemplatedColumn>

<CellTemplate>

<asp:LinkButton ID="linkBtn" runat="server" CommandArgument='<%#DataBinder.Eval(Container.DataItem,"SampleDataCount")%>' CommandName="SampleDataCount" ForeColor="#3F0400" ><%#DataBinder.Eval(Container.DataItem,"SampleDataCount")%></asp:LinkButton>

</CellTemplate>

</igtbl:TemplatedColumn>

</Columns>
