Your buttons need to be created BEFORE page load for viewstate to be restored and your events to fire.

To partial update I use the repeater within a Updatepanel. Is it problem to create a button BEFORE page load?
Just now I see that button is work well without using Updatepanel. But I want to partial update the page. Plz help.

Yes, viewstate is restored early, so your button needs to exist prior to page load, in order for viewstate to be restored.

Thanks
Plz hear my real problem. It a big problem to me
I have a page Connection.aspx that shows all connections(friends) of a user like faecbook and plaxo.com
I need to delete a connection when the user click on delete button()
and after deleting he see his new connection list on that page.
To do this
I use a updatepanel, repeater and usercontrol(profile.ascx).
Repeater set in the updatepanel. By repeater all connection show in Connection.aspx using usercontrol(profile.ascx).
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Repeater ID="repConnections" runat="server" OnItemDataBound="repConnections_ItemDataBound">
<ItemTemplate>
<div class="friendBody">
<Kooras:ProfileDisplaySmall ShowConnectionRequestButton="false" ShowDeleteButton="true" ID="pdProfileDisplay" runat="server" />
</div>
</ItemTemplate>
</asp:Repeater>
</ContentTemplate>
</asp:UpdatePanel>
profile.ascx have a delete button to delete connection.
When user click on that button, connection actually deleted. but page connection.aspx not be updated.
To solve this problem I think following technique
I place a button on connection.aspx set visiable false. and after clicking on delete button of the usercontrol(profile.ascx). the button on connection.aspx will be fire.
Dear........
If this is right way , Plz tall me how can I Implement it.

I think you should use a gridview, which is set up to handle things like delete buttons. I think you should experiment if using AJAX controls is also killing what you're trying to do. I also think you'd have a lot more control if you learned AJAX instead of blindly using the MS library.

Hello Boss
I also know about Gridwiew. and the problem can be solve by it. But I want to Implement like plax.com's request connection service.
In www.plaxo.com when a user click on request to connect link. A connection connection request send. page automatically updated and when a user click on cross button the deletion also fairly done.
Could you Suggest me more?

Use
<asp:Button ID="ConnectionDelete" runat="server" Text="Delete" OnCommand="ConnectionDelete_Click"/>
Inside Repeater, the button.click event is not generated. Rather OnCommand will be evaluated.
Also you can use CommandArgument if you want any arguments while the event is generated.
Inside the eventhandler you can use
e.CommandArgument or e.CommandName to handle the command properly.
Hope this help u.

Hi,
i would like to know whether there is any way ,
to block the user from copying images from the website other than disabling right clicking using javascript

This is useless. Anyone can beat it.
There is no way to protect images. If I can view the images on your site, no matter what you try to do, I can copy them.

You can disable right click on the page with javascript but some people can get around it.

Hi,
I bind the gridview to excel in disconnected mode. works fine.
MAke changes to gridview data. changes happen and reflected in dataset.
Try to update the dataset using adapter (to transfer the changes to same excel in connected mode). commandbuilder thorws exception as it is not able to find a primary key in excel sheet. How to do it?
public partial class excel_excel_disconnmode : System.Web.UI.Page
{
OleDbConnection oo;
OleDbDataAdapter adp;
DataSet ds;
protected void Page_Load(object sender, EventArgs e)
{
oo = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\\ASP1\\Book1.xlsx;Extended Properties=Excel 12.0");
adp = new OleDbDataAdapter("select ID from [Sheet1$]", oo);
if (!IsPostBack)
{
ds = new DataSet();
ViewState["ds"] = ds;
adp.Fill(ds, "sheet1");
GridView1.DataSource = ds;
GridView1.DataBind();
}
else
{
ds = (DataSet)ViewState["ds"];
GridView1.DataSource = ds;
}
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex; // turn to edit mode
GridView1.DataBind();
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
int pos = e.RowIndex;
ds.Tables[0].Rows[pos].Delete();
GridView1.DataBind();
}
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int pos = e.RowIndex;
string name = ((TextBox)GridView1.Rows[pos].Cells[0].Controls[0]).Text;
ds.Tables[0].Rows[pos][0] = name;
GridView1.EditIndex = -1;
GridView1.DataBind();
}
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
GridView1.EditIndex = -1;
GridView1.DataBind();
}
//to trasnfer the changes from disconnected to connected excel
protected void Button1_Click(object sender, EventArgs e)
{
adp = new OleDbDataAdapter("select ID from [Sheet1$]", oo);
OleDbCommandBuilder xx = new OleDbCommandBuilder(adp);
adp.Update(ds, "sheet1");
}
}

I am not sure where you are putting this code, or why you expect it to work. There are plenty of articles on using checkboxes in grids.

Hello All,
I am creating a class in C# for some functionality and later consuming it in my ASP.Net application.
I have written Try-Catch blocks in that class.
If an exception occurs, i want to display some message to user in Alert Box.
I am trying to generate alert box from below code
catch(System.Exception ex)
{
Response.Write("<script>alert('" + ex.Message + "');</script>");
}
But its showing compile time error : "The name 'Response' does not exist in the current context"
Am i missing something?
Thanks,
Nagendra.

That's odd. Where are you writing this code ? Not in a page class, I assume, otherwise the Response object would be there.

Hi,
I am writting this code in a C# class.
But i solved the above error by writting :
catch(System.Exception ex)
{
HttpContext.Current.Response.Write("<script>alert('" + ex.Message + "');</script>");
}
But its not showing Alert Box on exception.

Are you sure code is hitting the exception? Put a break point and check that first.
|
|
|
|
|
Yes it is showing exception.
Its also going over that alert box code but still alert box is not displayed.
If i am just writing the exception on page like
HttpContext.Current.Response.Write(ex.Message);
its showing the exception but not the alert box.
|
|
|
|
|
Use this....
Page page = HttpContext.Current.Handler as Page;
if (page != null)
{
ScriptManager.RegisterStartupScript(page, page.GetType(), "msg", "alert('Hi..')", true);
}
|
|
|
|
|
I tried but its showing error: "The name 'ScriptManager' does not exist in the current context"
|
|
|
|

Everyone is assuming you're writing script inside your page. That you're not, is bad design. You should fix that, catch the exception in your presentation layer, and do it there. I agree, using the script manager is a good idea. It is an object on the page class, so you can access it that way.
