Your Problem state clearly that you did not handle a RowEditing Event. If you are using a SQL Datasource this error will not occur. But i support what you are doing than using wizards to do your database work. What you need to do is to
protected void GridView1_OnRowEditing(object sender, GridViewDeleteEventArgs e)
{
}

You need to check the session value on every page load. if this value is null redirect user to login page,

Keep Session timeout in web .config file.It automatically handles session timeout value..!
Check the below settings ,Check sessiontomeout..!
<system.web>
<authentication mode="Forms">
<forms loginUrl="Login.aspx"
protection="All"
timeout="30"
name=".ASPXAUTH"
path="/"
requireSSL="false"
slidingExpiration="true"
defaultUrl="default.aspx"
cookieless="UseDeviceProfile"
enableCrossAppRedirects="false" />
</authentication>
</system.web>

It would be better to use asp.net Profile. Google about it and you'll get understanding of it.

Design a gridview with template columns and add button on the last column. In the button click event handler, add a new row to the grid's datasource and Bind().
Best wishes,

I have a User Control with a property declared internal bool AllowAllDepartments { get; set; }. However, whether I declaratively set this property where the control is sited, e.g. '...AllowAllDepartments="True"...', or programmatically in the Page_Load of the host page, when I hit a breakpoint in the Page_Load of the user control, the property still has a value of false. What am I doing wrong?
|
|

|

I have no idea. What happens if you factor this out so you have actual get and set methods you can put a breakpoint in ? That way, you can see if they are being set at all, and/or set when you don't intend it.

If you are using just this
internal bool AllowAllDepartments { get; set; }
it is impossible to have value false just after execution of the line
AllowAllDepartments= true (I removed Quotations" as they are not necessary)
If this is not so, it might be the case that you forgot to set the value to local variable in setter of the property and/or you didnt get the appropriate value from the variable in getter property.

Hello,
I have one treeview in updatepanel and one asp pannel(with visible = "false") out-side updatepanel.
On selectedIndexchanged of treeview, I want a pannel outside of updatepanel needs to be visible.
But it is not working. Is there any work around so that I can make my pannel visible w/o postback?
Thanks in advance.
Regards,
Milind.

If it's not inside an update panel, then you'd need to write your own javascript to make it visible.

All the content that is inside the Update panel will be posted back to the client and refreshed in the client as response. So it is impossible to update controls outside updatepanel from the server.
As Christian suggested, you need to pass some Javascript to the client which might show the Panel.
But there is another scenario. ASP.NET doesnt render controls that are made Visible=false. So from client side using javascript, you will not going to find the control.
So the solution will be :
1. Use pnl.Style.Add(HtmlTextWriterStyle.Display, "none") to make the panel invisible instead of pnl.Visible=false //To ensure that pnl is rendered in the client.
2. In postback of UpdatePanel use RegisterStartupScript to pass a javascript that resets the pnl.style. Your javascript might look like
"document.getElementById('" + pnl.ClientId + "').style.display='none';"
|
|
|
|
|
Or you could put ASP:Panel inside another update Panel and set it's update mode to Always,
But I think javascript will still be better

I think there must be some other css which overrides this. Check out.
You Can make a css class for the same and add using javascript when mouse comes over the anchor. Its an easy fix.
Or you can also use span to behave similar to anchor. Use onclick to navigate in span.
You can take either approach I think.
