To where you are adding this? To a new column?

Hard to give suggestions without seeing the code.

I am binding a dataset to a Gridview.

Gridview1.DataSource = dtTable;
GridView1.DataBind();

And in the GridView1_RowCreated() method
I add the usercontrol for each row.

TableCell cell = new TableCell();
e.row.cells[0].Add(LoadControl("~/Usercontrol1.ascx"));

Hope that clears it.

var panelControl = document.getElementById(panelControl);

Please pass the actual proper id to the method. I guess it should be panelControlId

Shouldn't this be var panelControl = document.getElementById(panelControlId);?

meeram395 wrote:

Don't you need a single quote (')? OnClick="SetCopyPermissionsControlState('CopyPermissionsPanel',this)

When you are using server control id in JS, best practice is to use ClientId. Your code will break if you plan to make the panel as a child of some other container control because ASP.NET will change the name when it render the control.

Browsers only understand HTML. ASP.NET will convert ASP:Panel to HTML DIV (not sure) when it is rendering the page. So you don't see ASP:Panel in the view source.

I have removed the panel control and I put an id to row.Now it is working fine. Following is the codew:

<tr><td class="labeltext"><asp:CheckBox ID="chkCopyPermissions" runat="server" Text = "CopyPermissions"
OnClick="SetCopyPermissionsControlState('CopyPermissionsRow',this)" /></td>
<td><asp:Label ID="lblCopyPermissionMessage" runat="server" ></asp:Label></td>
</tr>
<tr id="CopyPermissionsRow" visible="false">
<td class="labeltext">
<asp:Label ID = "lblCopyPermissions" runat = "server" Text = "Existing UserName" ></asp:Label>
</td>
<td>
<asp:TextBox id = "ExistingLoginTextBox" runat="server" TextMode="SingleLine" MaxLength="50"></asp:TextBox>
<asp:Button ID = "CopyPermissionsButton" runat="server" Text="Copy" OnClick="CopyPermissionsButton_Click" />
</td>
</tr>

Because of the above change, the javascript function , SetCopyPermissionsControlState, is firing now. But the issue is, I made it visible=false when the page loads which is not happening. The page loads by displaying the controls. However, when I check the checkboxes, it is changing accordingly. Any idea why it is not happening for the first time?

I don't want postback, because there is a password textbox in the form which erases the value on postback.

Following is my javascript function:

function SetCopyPermissionsControlState(rowControlId, checkBox) {

            var enabled = checkBox.checked;
            alert("enabled" + enabled);
            var rowControl = document.getElementById(rowControlId);
            alert("panelControl" + rowControl);

            if (rowControl) 
            {
                if (enabled) 
                {
                    rowControl.style.display = '';
                    
                }
                else 
                {
                    rowControl.style.display = 'none';
                  
                }
            }

        }

try to make auto post back property = true;

meeram3959-Jul-09 22:23

9-Jul-09 22:23

I don't want autopostback property to true, since there is a password textbox in the page which is losing value on postback. so everytime there is a postback, the user has to retype which is quite cumbersome.
Is there any other way?

In the HTML I have -

<%#ShowProjectUrl(Eval("website_url").ToString())%>

In the code behind I have -

protected string ShowProjectUrl(string projectUrl)
{
if (projectUrl != String.Empty)
return "<br />Project URL - <a href='" + projectUrl + "' target='_blank'>" + projectUrl + "</a><br /><br />";
else
return String.Empty;
}

The website is stored in the DB as www.XXX.com and passes to the function OK.

But when I click on the hyperlink at run time it navigates to -

http://localhost/www.XXX.com

If anyone know hoe to get rid of the localhost, it would be most appreciated.

Thanks.

Not sure resx files can be used to put JS. They are mostly used to create localizable applications. Here[^] is a quick start article.

Are you trying to embed JS with your web control? If yes, read this[^] article. I have explained the tricks to embed JS in that article.

Big Grin | :-D

public string HeaderBackground
{
get
{
string BgUrl = _NavigationBar.Page.ClientScript.GetWebResourceUrl
(_NavigationBar.GetType(),
"System.Web.UI.WebControls.headerbg.gif");
return BgUrl;
}
}

can u xplain bout dis :

_NavigationBar = should be what control?
"System.Web.UI.WebControls.headerbg.gif" = must be declare 1st like this
[assembly: System.Web.UI.WebResource ("System.Web.UI.WebControls.headerbg.gif",
"text/js", PerformSubstitution = true)] or not? Frown | :(

<Assembly: Web.UI.WebResource("MyControl.Resources.Myjs.js", "text/javascript")>
3rd : i put it in my render control
Me.Page.ClientScript.RegisterClientScriptResource(Me.GetType, "MyControl.Resources.Myjs.js")

Protected Overrides Sub Render(ByVal output As HtmlTextWriter)
Me.Page.ClientScript.RegisterClientScriptResource(Me.GetType, "MyControl.Resources.Myjs.js")
End Sub

where Me is myclass name = my Custom Control,MyControl is my namespace @ assembly name and Myjs.js is my javascript file..

n my output is :

<script src="/ReMS_V2/WebResource.axd?d=D1IqeTAdOjDfP0pZ9VBGJC-POAEpivg68Tt8d3nvvohjhpvlLabTCUAvuIwMxtheqPLpIETzl0dZbENpenxOng2&t=633828360951397648" type="text/javascript"></script>

That code shows embedding the image into the assembly. I'd suggest to download the code provided with that article. Try to create a simple control by referring that code. If everything is OK, move that to your main project.

Read MSDN documentation about the methods used. It will help you to get started.

It can be any type. Me.GetType should do.

You need fully qualified path which starts from the namespace name.

Yes. You need your file name here. MSDN[^] has an example which will get you started.
