How do I check if there is an index in the column.

ASKER

I am not sure what the error means

"Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"

I am not really sure how to use the watch window.

Here is a screen shot of my watch window. Is it possible for you to mark on it where I have to look.

Look at the Columns. Are there any Columns in the gridview?

ASKER

yes. my gridview is populated.... i just need to expand one of the columns.

Check whether the gridview has column collection by clicking '+' sign before Columns in watch window. If you then after binding keep the piece of code specified by Harry/dev

ASKER

hmm not sure... here is a screen shot for you to have a look.

Shall I put the piece of code specified by Harry/dev in the page load or on RowDataBound

Use Column index as 0 not 1

ASKER

Ok.. now error..

But how do i specify which column I want to change the width..

You can specify the column name or column index. your snapshot shows only one column. So index will be 0

dataGridView1.Columns[0].Width = 100;

or

If (Referral_Gridview.Columns != null && Referral_Gridview.Columns.Count >0)
{
Referral_Gridview.Columns[0].ItemStyle.Width = Unit.Pixel(100);
}

as Harry/Dev said

ASKER

I have ten columns.

I am binding my data dynamically

example
gridview1.datasource = dataset;
gridveiw.databind();

Specify Columnm name instead of index

If (Referral_Gridview.Columns != null && Referral_Gridview.Columns.Count >0)
{
Referral_Gridview.Columns["Col1"].ItemStyle.Width = Unit.Pixel(100);
}

ASKER

it does not like me putting a string in place of an int

can you post your code?

ASKER

Referral_Gridview.Columns["Providers"].ItemStyle.Width = Unit.Pixel(100);

The Columns overload is an int not a string.

Can you post the part of code where you are binding data assigning col width

ASKER

Referral_Gridview.DataSource = DataSet1;
Referral_Gridview.DataBind();

Referral_Gridview.Columns["Providers"].ItemStyle.Width = Unit.Pixel(100);

--> Referral_Gridview.DataSource = DataSet1;
Referral_Gridview.DataBind();

Referral_Gridview.Columns["Providers"].ItemStyle.Width = Unit.Pixel(100);

At the arrowed point pls keep breakpoint and check the data in dataset

ASKER

the syntax which you are suggesting will not work because Column[ ] requires a int overload not a string.

You can have index. thats fine. Look at the dataset and check whether do u have any data or not?
