Hi

I have created the nested gridview, parent and child.
Now I want to clone the child gridview after clicking on button. It should be cloned in same parent gridview.

Child gridview has the rowbind function, that should be applied to cloned grid

Is there any way to do this, Please Help Me.

Bellow is the code that i have tried


C#

protected void Button1_Click(Object sender, CommandEventArgs e)
{
string Partid = e.CommandArgument.ToString();
//datakey is assigned on grid control as DataKeyNames="UnivercityCode"
// string id1 = universityGrid.DataKeys[e.Row.RowIndex].Value.ToString();
//data table cloing
GridView gr1 = new GridView();
gr1.ID = "gvattrgrid";
gr1.HeaderStyle.CssClass = "attheaderstyle";
gr1.RowStyle.CssClass = "attrowstyle";
gr1.AlternatingRowStyle.CssClass = "attalterrowstyle";
gr1.CssClass = "attgridwidth";
gr1.CellPadding = 8;
gr1.AutoGenerateColumns = false;
gr1.CellSpacing = 10;
Table t = new Table();
gr1.Controls.Add(t);
foreach (GridViewRow row in gvPartGrid.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{

GridView gvChild = (GridView)row.FindControl("gvattributeGrid");

DataTable dt = new DataTable();
for (int i = 0; i < gvChild.Columns.Count; i++)
{
dt.Columns.Add("column" + i.ToString());
}
foreach (GridViewRow row2 in gvChild.Rows)
{
DataRow dr = dt.NewRow();
for (int j = 0; j < gvChild.Columns.Count; j++)
{
dr["column" + j.ToString()] = row2.Cells[j].Text;
}

dt.Rows.Add(dr);
}

DataTable dtClone = dt.Clone();
gr1.DataSource = dtClone;
gr1.DataBind();
}
}
TextBox txtSearch = new TextBox();
txtSearch.ID = "txtSearch";
for (int i = 0; i < gvPartGrid.Rows.Count; i++)
{
//TextBox txtqty = (TextBox)gvPartGrid.Rows[i].FindControl("txtqty");
PlaceHolder appendgrids2 = gvPartGrid.Rows[i].FindControl("PlaceHolder1") as PlaceHolder;

string partid = gvPartGrid.Rows[i].Cells[1].Text;

if (partid == Partid)
{
appendgrids2.Controls.Add(txtSearch);
appendgrids2.Controls.Add(gr1);
}
}

}

Member 11826979 10-Jul-15 2:32am    
I have tried trough c# but not able to clone and append to placeholder. I dont know what i m making mistake.Bellow is the code that i have tryed

protected void Button1_Click(Object sender, CommandEventArgs e)
{
string Partid = e.CommandArgument.ToString();
//datakey is assigned on grid control as DataKeyNames="UnivercityCode"
// string id1 = universityGrid.DataKeys[e.Row.RowIndex].Value.ToString();
//data table cloing
GridView gr1 = new GridView();
gr1.ID = "gvattrgrid";
gr1.HeaderStyle.CssClass = "attheaderstyle";
gr1.RowStyle.CssClass = "attrowstyle";
gr1.AlternatingRowStyle.CssClass = "attalterrowstyle";
gr1.CssClass = "attgridwidth";
gr1.CellPadding = 8;
gr1.AutoGenerateColumns = false;
gr1.CellSpacing = 10;
Table t = new Table();
gr1.Controls.Add(t);
foreach (GridViewRow row in gvPartGrid.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{

GridView gvChild = (GridView)row.FindControl("gvattributeGrid");

DataTable dt = new DataTable();
for (int i = 0; i < gvChild.Columns.Count; i++)
{
dt.Columns.Add("column" + i.ToString());
}
foreach (GridViewRow row2 in gvChild.Rows)
{
DataRow dr = dt.NewRow();
for (int j = 0; j < gvChild.Columns.Count; j++)
{
dr["column" + j.ToString()] = row2.Cells[j].Text;
}

dt.Rows.Add(dr);
}

DataTable dtClone = dt.Clone();
gr1.DataSource = dtClone;
gr1.DataBind();
}
}
TextBox txtSearch = new TextBox();
txtSearch.ID = "txtSearch";
for (int i = 0; i < gvPartGrid.Rows.Count; i++)
{
//TextBox txtqty = (TextBox)gvPartGrid.Rows[i].FindControl("txtqty");
PlaceHolder appendgrids2 = gvPartGrid.Rows[i].FindControl("PlaceHolder1") as PlaceHolder;

string partid = gvPartGrid.Rows[i].Cells[1].Text;

if (partid == Partid)
{
appendgrids2.Controls.Add(txtSearch);
appendgrids2.Controls.Add(gr1);
}
}

}

Instead of creating dynamic grid control to clone, you can replace PlaceHolder control have another grid control which is Visible = false in your parent grid control, to hold clone data.

Now on your button click you just assign data and make it visible when it matching your condition of PartID for current row only. For this you need to maintain datasouse for parent grid control at common place e.g. page level variable.

It will be simple approach I think instead of having dynamic grid creation.

Is it possible to clone more than one
