I am trying to use a tool tip on every row of a grid to show details whenever user place pointer on particular cell. It's supposed to show details for every row but it only shows details for the first row. Can any one help me?
for (int i = 1; i <= e.Row.Cells.Count - 1; i++)
{
if (e.Row.Cells[i].Text == "0" || string.IsNullOrEmpty(e.Row.Cells[i].Text) || e.Row.Cells[i].Text == " ")
{
e.Row.Cells[i].Text = "";
}
else
{
e.Row.Cells[i].BackColor = System.Drawing.Color.Blue;
dateSetExport.Tables.Clear();
dateSetExport.Reset();
SqlParameter[] param = new SqlParameter[2];
param[1] = new SqlParameter("#Startdate", gvDetails.HeaderRow.Cells[i].Text);
param[0] = new SqlParameter("#Employe_Id", e.Row.Cells[0].Text.Split('-')[0]);
DataTable dt1 = DataHelper.getDataTableExecuteSP("usp_GetToolTip", param);
dt1.TableName = "ToolTip";
dateSetExport.Tables.Add(dt1);
string tooltip = "";
for (int j = 0; j < dt1.Rows.Count; j++)
{
tooltip = tooltip + dt1.Rows[j]["normal_working_hours"].ToString() + " Hours : " + dt1.Rows[j]["description"].ToString()+"\n\n";
}
e.Row.Cells[i].ToolTip = tooltip;
}
}
You can use another foreach in order to loop all rows :
foreach (GridViewRow row in GridView.Rows)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//do your staff
}
}
But for me, you should use GridView_RowDataBound event :
protected void GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
for (int i = 1; i <= e.Row.Cells.Count - 1; i++)
{
if (e.Row.Cells[i].Text == "0" || string.IsNullOrEmpty(e.Row.Cells [i].Text) || e.Row.Cells[i].Text == " ")
{
e.Row.Cells[i].Text = "";
}
else
{
e.Row.Cells[i].BackColor = System.Drawing.Color.Blue;
dateSetExport.Tables.Clear();
dateSetExport.Reset();
SqlParameter[] param = new SqlParameter[2];
param[1] = new SqlParameter("#Startdate", gvDetails.HeaderRow.Cells[i].Text);
param[0] = new SqlParameter("#Employe_Id", e.Row.Cells[0].Text.Split('-')[0]);
DataTable dt1 = DataHelper.getDataTableExecuteSP("usp_GetToolTip", param);
dt1.TableName = "ToolTip";
dateSetExport.Tables.Add(dt1);
string tooltip = "";
for (int j = 0; j < dt1.Rows.Count; j++)
{
tooltip = tooltip + dt1.Rows[j]["normal_working_hours"].ToString() + " Hours : " + dt1.Rows[j]["description"].ToString()+"\n\n";
}`enter code here`
e.Row.Cells[i].ToolTip = tooltip;
}
}
}
}

}
}
I was finally able to solve my problem by hardcoding in the following:
//Hide and show fields
protected void UnverifiedSalesGV_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex == rowIndex)
{
string state = e.Row.RowState.ToString();
if (state == "Alternate, Edit" || state == "Edit")
{
//Get record ID
string salesID = UnverifiedSalesGV.DataKeys[Convert.ToInt32(e.Row.DataItemIndex)].Value.ToString();
//Get productID
SalesData getSalesRecord = new SalesData();
getSalesRecord.GetRowValuesSalesID(salesID);
string productID = getSalesRecord.productID;
if (productID == "38")
{
//Items to Hide/Display
Button UpdateProductBTN = (Button)e.Row.FindControl("UpdateProductBTN");
Button UpdateBTN = (Button)e.Row.FindControl("UpdateBTN");
Label productLBL = (Label)e.Row.FindControl("CurrentProductLBL");
Label accountManagerLBL = (Label)e.Row.FindControl("AccountManagerLBL");
DropDownList productDDL = (DropDownList)e.Row.FindControl("RenewalProductDDL");
DropDownList accountManagerDDL = (DropDownList)e.Row.FindControl("AccountManagerDDL");
Label grossSalesLBL = (Label)e.Row.FindControl("GrossSalesLBL");

UpdateProductBTN.Visible = true;

I am creating a datatable and adding rows dynamically and am binding datatable to gridview when there are no records am displaying as no records found using emptydatatext but this is not working.Here is my code

string fence_start_date_time1 = common.get_request("fence_start_date_time");

//Delete data from datatable and gridview
dt_fence.Clear();

In your code you're assigning EmptyDataText value after DataBind. It should be before DataBind. If "Message" is not going to change, you should rather define in HTML source as suggested.
You can use something like this
<Columns>
<Columns>
<EmptyDataTemplate>
<asp:Label ID="lblEmptydata" runat="server" Text="No Data here"></asp:Label>
</EmptyDataTemplate>
</asp:GridView>
Or can try this
in my remark gridview's row_databoundevent i wrote
if (e.Row.Cells[0].Text == " ") // to display text when there is no data
{
e.Row.Cells[0].Text = "No Data Found";
}
Or can try this too
dt.Rows.Add(dt.NewRow());
grid1.DataSource = dt;
grid1.DataBind();
int totalcolums = grid1.Rows[0].Cells.Count;
grid1.Rows[0].Cells.Clear();
grid1.Rows[0].Cells.Add(new TableCell());
grid1.Rows[0].Cells[0].ColumnSpan = totalcolums;
grid1.Rows[0].Cells[0].Text = "No Data Found";
