推荐答案

Hello，
为此
1st:创建数据表
第二个:将行添加到数据表
第三步:绑定到gridview并将其存储在viewate中，然后从第1步开始重复(通过将viewstate值转换回datatable)


第一步:
按照以下方式创建数据表...
DataTable表=新的DataTable();
添加所需的列数，并提供要绑定到gridvieww的名称.

table.Columns.Add("Ename"，typeof(int));
table.Columns.Add("Sname"，typeof(string));
table.Columns.Add(部门"，typeof(字符串));
table.Columns.Add("DateOfJoin"，typeof(string));

第二步:
按钮的onclick会取在文本框中输入的值，然后添加到数据表的列中.

table.Rows.Add(txtname.text.trim()，txtsname.text.trim()，txtDptName.text.trim()，txtdate.text.trim());

最后将此表绑定到gridview
grdEmpdetails.datasource = table;

并将此表存储在viewstate
viewstate ["dtTable"] = talbe;
再次
第三:单击按钮后，您必须将viewstate值转换回datatable并添加新行，然后再次将其绑定到gridview ..

完成

Hello,
To Do this

table.Columns.Add("Ename", typeof(int));
table.Columns.Add("Sname", typeof(string));
table.Columns.Add("Department", typeof(string));

2nd step:
onclick of the button take the values entered in the textbox and add to the columns of the datatable.

table.Rows.Add(txtname.text.trim(),txtsname.text.trim() ,txtDptName.text.trim(),txtdate.text.trim() );

at the end bind this table to the gridview
grdEmpdetails.datasource=table;

and store this table in the viewstate
viewstate["dtTable"]=talbe;
