You can't change what ASP.NET renders, unless you write your own image button control.

I don't think that the issue is your button, actually, I think it's other controls on your form. You'd have to experiment to find out. I think that this line of questioning in Firefox is new, and so there's a collision. The FF people either didn't test it, or didn't care that it doesn't work nicely with ASP.NET sites.

The alternative is that you have some sort of password text box on your form, for whatever reason, and that's the cause.

Hello

Im must read records from Gridview and then insert them to database.
Here is the code that I wrote.

 <br />
for (int i = 0; i<counter; i++)  <br />
        {<br />
            string ID = GridView.Rows[i].Cells[0].Text;<br />
           objDataAdapter.SelectCommand.CommandText = "INSERT INTO MYTable " +<br />
            "(Name) VALUES(@Name)";<br />
            objDataAdapter.SelectCommand.Parameters.AddWithValue("@Name",Name);<br />
}<br />

There is an exception:

The variable name '@Name' has already been declared. Variable names must be unique within a query batch or stored procedure.

Please help me how can I handle this exception.

Does this happen the first time through, or the second ?

Why would you make the 'select command' do an insert ? Why not just run the SQL directly without using a data adapter ?

The problem solved with this: Wink | ;)

objDataAdapter1.SelectCommand.Parameters.Clear();

OK, that's what I suspected, because it's a member object, you're setting the parameter over and over, that's why I asked if it happens the first time.

I think those data adapter things are retarded, I never use them.

What do you use instead of adapter?

ViewState Probelm in GridView

30-Jul-09 12:28

I write a proper data layer, in a seperate dll, I NEVER put SQL in the presentation layer, and I'd fire anyone who worked for me who did.

Hi ...

I have bind one gridview with 2 different Method.

Total 250 records are there.

In first Method I fetch all 250 record in dataset and bind in Gridview with EnablePaging = True. Mean while i am saving this dataset in view state.Here grid view show only 10 records per page.

So now when i see page source it display size of view state around 28 kb.

In second method I fetch page wise record from DB. Means for 1st page i am fetching 10 record. and storing this dataset(with only 10 records) in view state for sorting.

Now when i see page source it display the same size in view state.

Is there any other technic to reduce view state??

and why happen like this in first method it fetch 250 records and i am storing it in view state while in second method i fetch only 10 records and storing in view state still view state size remain same.

Hard to say without seeing the code. What happens if you disable viewstate in the gridview, how much does it drop by then ? That will tell you how much of the viewstate is your data in the gridview

Hi christian,

i have already disable view state for some of the column in grid view.

After binding gridview i am reading one by one row and each and every row i am go thorugh cells one by one and disable this cells enableviewState property to false.

in this way if i am doing than it is reduce viewstate from 32kb to 27 kb.

but problem is that first method fetch 250 records and i am storing this records in viewstate for later paging & sorting

& in second method i am fetch first 10 records and storing this record in view state for later sorting only. when i click second number in paging than i am fetching record from 11 to 20 and storing this one to view state.

just my problem is to when i see view source of aspx page at that time in both the case it showing me viewstate size as 27 kb only.why it is not reduced...???? In first case i have store 250 rows while in second one i have stored 10 rows in view state..

Regards,
Hemant Patel.

Dynamic link button controls

30-Jul-09 11:36

Asking me the same question again is not helpful. Did you disable viewstate for the entire grid ? If you did, then any viewstate you're seeing, is from other things on your page.

Hello I am trying to create linkbutton controls that are supposed to fire method. I add them to pageload however I am told that I should add them before it. I google the lifecycle and I found 2 events Init and PreLoad, I tried them and they are really fired before page_load however this time the controls even do not appear. here is the code:

protected void Page_Preload()
{
for (int i = 1; i <= 2; i++)
{
LinkButton bottomLink = new LinkButton();
LiteralControl bottomLiteral = new LiteralControl(" ");
bottomLink.Text = i.ToString();
pnlBottom.Controls.Add(bottomLink);
pnlBottom.Controls.Add(bottomLiteral);
bottomLink.OnClientClick += new EventHandler(this.changeLink);

}
}

it is drawing me crazy please help.

Where is parameter Object and EventArgs ?

Try this. Its work for me Big Grin | :-D

protected void Page_Preload(object sender, EventArgs e)
    {
        for (int i = 1; i <= 2; i++)
        {
            LinkButton bottomLink = new LinkButton();
            LiteralControl bottomLiteral = new LiteralControl(" ");
            bottomLink.Text = i.ToString();
            pnlBottom.Controls.Add(bottomLink);
            pnlBottom.Controls.Add(bottomLiteral);
            bottomLink.Click += new EventHandler(bottomLink_Click);
         }
    }

I will suggest you to create all the control on Pre_Init()

Thanks for the reply but it is not working. Smile | :)

. That why I am getting crazy. Smile | :)

Do you think pnlBottom (panel) would be created before_preinit, since I added it on HTML page...

Thanks again.
