I have 2 tyext boxes:
1)varchar Text box
2)numeric Textbox
'SUBMIT' Buttton.
There is a DataGrid below this submit button.
I had dynamically created this datagrid and Added data.
While I am editing the values,Sometimes user may add some more items into the
datagrid.For me it show only new datagrid value.
I need to append the values below the edited datagrid values.
private void Btn_addlist_Click(object sender, System.EventArgs e)
{
DataSet dstReqObj=new DataSet();
if(ItemsGrid.Items.Count>0)
{
display();
}
else
{
display();
}
}
private void display()
{
DataView dvView=new DataView();
dvView= CreateDataSource();
ItemsGrid.DataSource =dvView;
// Response.Write(i);
ItemsGrid.DataBind();
Session["ItemData"]= dvView;
}
public DataView CreateDataSource()
{
DataTable dt = new DataTable("answerblock");
DataRow dr;
DataColumn colResult;
DataColumn[] keys = new DataColumn[1];
DataView dvView=new DataView();
if(Session["ItemData"]==null)
{
DataSet dstReqObj=new DataSet();
Session["ItemData"]=dstReqObj;
//CheckBox deleteChkBxItem = (CheckBox) CurRow.FindControl("del");
colResult=new DataColumn("SNO",Type.GetType("System.Int32"));
colResult.AutoIncrementSeed=1;
colResult.AutoIncrement=true;
keys[0] = colResult;
dt.Columns.Add(colResult);
colResult=new DataColumn("Answer",Type.GetType("System.String"));
dt.Columns.Add(colResult);
colResult=new DataColumn("Value",Type.GetType("System.String"));
dt.Columns.Add(colResult);
dt.PrimaryKey=keys;
dstReqObj.Tables.Add(dt);
}
else
{
dvView=(DataView)Session["ItemData"];
dt=dvView.Table;
}
int i=dt.Rows.Count+1;
if(i<=1)
{
dr=dt.NewRow();
dr[1]=Tbx_ans.Text;
dr[2]=Tbx_defans.Text;
dt.Rows.Add(dr);
DataView dv = new DataView(dt);
return dv;
}
else
{
dr=dt.NewRow();
dr[1]=Tbx_ans.Text;
dr[2]=Tbx_defans.Text;
dt.Rows.Add(dr);
DataView dv = new DataView(dt);
return dv;
}
