How can I export GridView.DataSource to datatable or dataset?


Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.

Method 1

Assuming your DataSource is of type DataTable, you can just do this:

myGridView.DataSource as DataTable

Method 2

You should convert first DataSource in BindingSource, look example

BindingSource bs = (BindingSource)dgrid.DataSource; // Se convierte el DataSource 
DataTable tCxC = (DataTable) bs.DataSource;

With the data of tCxC you can do anything.

Method 3

Personally I would go with:

DataTable tbl = Gridview1.DataSource as DataTable;

This would allow you to test for null as this results in either DataTable object or null. Casting it as a DataTable using (DataTable)Gridview1.DataSource would cause a crashing error in case the DataSource is actually a DataSet or even some kind of collection.

Method 4


I was having the same issue as you, and this is the code I used to figure it out. Although, I don’t use the footer row section for my purposes, I did include it in this code.

    DataTable dt = new DataTable();

    // add the columns to the datatable            
    if (GridView1.HeaderRow != null)

        for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)

    //  add each of the data rows to the table
    foreach (GridViewRow row in GridView1.Rows)
        DataRow dr;
        dr = dt.NewRow();

        for (int i = 0; i < row.Cells.Count; i++)
            dr[i] = row.Cells[i].Text.Replace("&nbsp;","");

    //  add the footer row to the table
    if (GridView1.FooterRow != null)
        DataRow dr;
        dr = dt.NewRow();

        for (int i = 0; i < GridView1.FooterRow.Cells.Count; i++)
            dr[i] = GridView1.FooterRow.Cells[i].Text.Replace("&nbsp;","");

Method 5

If you do gridview.bind() at:



//your gridview bind code here...


Then you can use DataTable dt = Gridview1.DataSource as DataTable; in function to retrieve datatable.

But I bind the datatable to gridview when i click button, and recording to Microsoft document:

HTTP is a stateless protocol. This means that a Web server treats each
HTTP request for a page as an independent request. The server retains
no knowledge of variable values that were used during previous

If you have same condition, then i will recommend you to use Session to persist the value.


After that you can recall the value when the page postback again.

DataTable dt=(DataTable)Session["oldData"];


Method 6

I have used below line of code and it works, Try this

DataTable dt =  dataSource.Tables[0];

Method 7

This comes in late but was quite helpful. I am Just posting for future reference

DataTable dt = new DataTable();
Data.DataView dv = default(Data.DataView);
dv = (Data.DataView)ds.Select(DataSourceSelectArguments.Empty);
dt = dv.ToTable();
