How does C add a piece of content from one GridView to another? Thank you!

The algorithm is as follows: 1. Take a row from gridview1 and store it in datarow.

2. Add datarow to the gridview:;

datarow dr=;is the data source table of gridview1.

dr["a"]=;

dr["b"]=;

Above dr[.]"a"] is the name of the first column of GridView1 and the name of the first column of the data source table of GridView1.

For example, if the first gridview binds datatable to datatable1 and the second gridview binds datatable to datatable2, add a row from datatable1 (for example, the first row) to datatable2, and then rebind datatable2 to the second gridview

datarow row = ;;

1. Create a new form for testing, including a datagridview, datagridview has three columns, which are student number, name, and score to represent a final exam score table.

2. Double-click the Add Data button and fill in the Add Data**.

3. Click Run and fill in the data.

4. Click Add to add a row of data.

Notes:C is an efficient programming language that produces only a small number of machine languages and does not require any runtime environment support. Although C provides many low-level processing features, it still maintains its cross-platform nature.

First of all, you need to make sure that the AllowUserToAddRows property of your DataGridView is true, so that your last row is always the added row, and after adding the data, get the last row of data in your insert button event, DataGridViewRow row = ;

foreach (datagridviewcell item in

After that, you can do it.

private void tapein_load(object sender, eventargs e)

Add tape detail programs.

private void addbtn_click(object sender, eventargs e)

if ( ==

using (sqlconnection cn = new sqlconnection(

Initialize the datatable fields.

private void initdatatable()

Design a datagridview

private void bindgrid()

In fact, this is a very simple problem, first of all, bind the datagridview when displaying, that is, =dt; Because this is bidirectionally binding, we only need to add, delete and modify the data source (that is, operate on DT), which will be reflected in the DataGridView, that is, when the button is added: DataRow dr=;

dr["field"]=value.

Then update Update to the database and then.
