Meanwhile i found the way. Here is my code if anyone is curious about it:
protected void gvUsuarios_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Select")
{
GridViewRow gvr = ((GridViewRow)((LinkButton)((GridViewCommandEventArgs)e).CommandSource).Parent.Parent);
gvUsuarios.SelectedIndex = gvr.RowIndex;
}
}
protected void gvUsuarios_RowDataBound(object sender, GridViewRowEventArgs e)
{
GridViewRow gvr = ((GridViewRowEventArgs)e).Row;
if (gvr.RowType == DataControlRowType.DataRow)
{
if (gvUsuarios.EditIndex < 0)
{
LinkButton button = (LinkButton)gvr.Cells[1].Controls[1];
if (button != null)
{
gvr.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(button, "");
}
}
if (gvr.RowIndex == gvUsuarios.SelectedIndex)
{
gvr.Attributes.Add("onmouseover", "highlightRow(this, '#B0FF62')");
gvr.Attributes.Add("onmouseout", "dehighlightRow(this, '" + ColorTranslator.ToHtml(gvUsuarios.SelectedRowStyle.BackColor) + "')");
}
else
{
gvr.Attributes.Add("onmouseover", "highlightRow(this, '" + ColorTranslator.ToHtml(Color.White) + "')");
gvr.Attributes.Add("onmouseout", "dehighlightRow(this, '" + ColorTranslator.ToHtml(gvUsuarios.RowStyle.BackColor) + "')");
}
}
}

Hi,
I have searched for an example of an ASP.NET web site project which would serve as a good starter for any number of web applications.
I need to create a web site which manages a load of stock for someone and the first thing I have to do is build a website with a few users who have various roles, etc. I will need to create a login form, a password retrieval form, and so on.
Does anyone know of an article or example which provides this as a project I can just download and start working with, adding my own code as I need to rather than having to repeat a load of work which has already been done?
I think it would be great for Visual Studio to have a wizard to just build and configure a web site complete with membership, security and roles built in. Then we programmers could just get on with the non-bolierplate stuff.

Hi,
In my application, I enter a string as "Show
Names" in a text field which is in updatepanel. This string is stored in database. later on another page this string is used to populate the column header. The column header displays properly as
Show
Names
with break after the string "Show".
now I go back to previous page where it loads the values saved in database. There is a check box in the same update panel , clicking on it causes a postback. But then it causes a server error with code 500. It is caused by
string in the text field. At any cost I need this line break for the column header from the saved column header string.
How to resolve this issue?
Thanks

This is not helpful. You need to debug your code and see where it is breaking. Also uncheck "Show Friendly error" in the tools->Internet Options-> advanced menu, if you are running IE. that may be give you a better error.

Are you constrained to using Javascript? Otherwise, it's easy to access the template control from codebehind using the FindControl function. What are you trying to achieve? Again I think we need more code than you've provided for us to adequately help you.

Hi, I've designed a templated ASP.NET GridView Control. What I want to achieve is to change the HeaderText of one of the columns based on a DropDownList SelectedIndexChanged event. I placed a label into the HeaderTemplate:
<headertemplate>
<asp:label id="lblValueRate" runat="server" width="64px" xmlns:asp="#unknown">""
If a User selects 'Value' from the dropdownlist then I set the Text property of lblValueRate to 'Value' and if User selects 'Rate', changes to 'Rate'.
<asp:dropdownlist id="dbcValueRate" runat="server" autopostback="True" xmlns:asp="#unknown">
<asp:listitem>Rate <asp:listitem>Value
I've tried implementing it this way without success:
Label lblNew = (Label)GridView1.HeaderRow.FindControl("lblValueRate");
Then set lblNew.Text = Rate or Value
This didn't change the GridView Column Header so I thought perhaps I wasn't getting a reference to lblValueRate. So I tried using pointer in unsafe code, Like this:
Label* ptrLabel = &((Label)GridView1.HeaderRow.FindControl("lblValueRate"));
and dereferenced it this way: Label lblNew = *(ptrLabel);
But throws up error that can't get address of managed control.
I believe this is very trivial, but I seem stuck here. Thanks!

Yeah, I've solved the issue. The code works as it is. Made a few mix-ups elsewhere in code. It's interesting that the assignment,
Label lblNew = (Label)GridView1.HeaderRow.FindControl("lblValueRate");
copies the address as well, rather than just the value as we have, when we copy one variable to another? It was this consideration that made me consider using pointers as an alternative - thankfully, .NET does the 'dirty work' for you. Or so it seems.
Thanks everyone!

fckeditor is just an editor. You can use whatever editor your feel comfortable with.
I guess what you are looking for is User Controls[^].

I have several TextBox controls with initial values. When I tab between them, the OnFocus event blanks out the initial value by setting value="". When this happens, the caret disappears. This gives the user the impression that the control has lost focus, but it hasn't. This does not happen if you click in any of the TextBoxes with the mouse, only when tabbing into a TextBox. Any ideas?

Hello Everybody
I am using asp calendar control on my web page but its big according to the page i have set its width and height but its not resizing..
Thanks.

so first of all checkout size of that where your control is...
if i am not right then give some description or code..
thanks..
