lnkbutton is the ID of button which is in RadTreeview1 .
Code - Behind
protected void RadTreeView1_NodeExpand(object sender, RadTreeNodeEventArgs e)
{
string getc = "SELECT [User].Name, [User].ID, Comments.ID AS CID, Comments.Comment, Comments.ItemID, Comments.UID, [User].T28 FROM [User] INNER JOIN Comments ON [User].ID = Comments.UID WHERE (Comments.ItemID = 271)";
dt = dbClass.ReturnDT(getc);
if (dt.Rows.Count > 0)
{
int n = dt.Rows.Count;
for (int m = 0; m < n; m++)
{
RadTreeNode onDemandNode = new RadTreeNode();
onDemandNode.ImageUrl = dt.Rows[m]["T28"].ToString();
onDemandNode.Text = "<u><b><a href='Profile/profile.aspx?Id="+dt.Rows[m]["ID"].ToString()+"'>"+dt.Rows[m]["Name"].ToString()+"</a></b></u> "+ dt.Rows[m]["Comment"].ToString();
onDemandNode.ExpandMode = TreeNodeExpandMode.ClientSide;
//Add the node as a child of the currently expanded node
RadTreeView1.Nodes.FindNodeByText("Comments").Nodes.Add(onDemandNode);
}
}
}
protected void lnkbutton_Click(object sender, EventArgs e)
{
RadTextBox tb= (RadTextBox)RadTreeView1.Nodes.FindNodeByValue("pcomment").FindControl("postcomment");
string insertcomment = " INSERT INTO Comments (ItemID, UID, Comment) VALUES (271, "+Session["UserId"]+", '"+tb.Text+"')";
dbClass.DataBase(insertcomment);
}
What I want is ,whenever the user clicks the button post that is the button with ID lnkbutton , the RadTreeView1 gets refreshed (without reloading the whole page again) , what should i do to achieve this ??
