You can create a dummy DataTable and bind it to the GridView. It will show only the headers

Hi There,
I am posting a Sample hope it helps you,
if (sDataSet == null || sDataSet.Tables[0].Rows.Count == 0)
{
sDataSet.Tables[0].Rows.Add(sDataSet.Tables[0].NewRow());
GridView1.DataSource = sDataSet;
GridView1.DataBind();
int TotalColumns = GridView1.Rows[0].Cells.Count;
GridView1.Rows[0].Cells.Clear();
GridView1.Rows[0].Cells.Add(new TableCell());
GridView1.Rows[0].Cells[0].ColumnSpan = TotalColumns;
GridView1.Rows[0].Cells[0].Text = "No Record Found";
}
else
{
GridView1.DataSource = sDataSet ;
GridView1.DataBind();
}

you can use EmptyDataTemplate
<EmptyDataTemplate>
<table width="100%" border="0" cellspacing="0">
<tr style="background-color: #5D7B9D; font-weight: bold; color: White; width: 100%;">
<td>
Name </td>
<td>
Surname</td>
<td>
City</td>
<td>
Phone</td>
<td>
</td>
</tr>
</table>
</EmptyDataTemplate>

Assign an EventHandler to their Click event.
Experience is the sum of all the mistakes you have done.

They need to be created before page load, and the exact same buttons need to be created on postback, in the same order, so that viewstate can be restored and the events can fire.

Hi guys.
i can explain for my doubt with example.see.my table have multiple type of employee details like as Mangemment,Programmer,Designers,Accountants,Contra ctEmployees.Each type of department having many employee details.Now my drop down list having types of department names like that above types of department names..if i select any one type of department data wil be display in gridview format .gridview data column as employee Name,Address,Phone_No,email_address and each every row with checkboxes.gridview showing data according to select the dept.No problem.
first I select Mangemment type of employee grid view showing that type of employee details ,here i checked first two employee details then checkbox values put in one viewstate,then i go to Programmer type of employee it showing that type employee details here i want to checked two employee details using checkbox but what happened first two checkboxes are already checked. so view state having proper checked check box values but problem is
whenever i go to select for another type of employee details checkboxes are checked based upon order of previous checked index.
i checked checkbox values of dropdown list selected index changed event,values are coming from viewstate,so we want viewstate values add plus new checked checkbox values ,but if i click display button control that viewstate values are removing then new checked checkbox values are only diaplay .
see my code behind..
i can put tears smile near code where i used viewstate and i can qustioned smile near the code of viewstate values are removing( i mean previous page checked checkbox values).
Protected Sub gridview1_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gridview1.PageIndexChanging
gridview1.PageIndex = e.NewPageIndex
getselected()
databind1("First_name", "asc")
setSelected()
End Sub
------------------
Public Sub getselected()
Dim arrayListContactGroup As New ArrayList
 If ViewState("ArrayList") IsNot Nothing Then
arrayListContactGroup = CType(ViewState("ArrayList"), ArrayList)
ViewState.Remove("ArrayList")
End If
For Each row As GridViewRow In gridview1.Rows
Dim chkselectcontacts As CheckBox = CType(row.FindControl("chksel"), CheckBox)Dim arraylistlabel As Label = CType(row.FindControl("contid"), Label)
If chkselectcontacts.Checked Then
If Not arrayListContactGroup.Contains(arraylistlabel.Text) Then
arrayListContactGroup.Add(arraylistlabel.Text)
End If
Else
If arrayListContactGroup.Contains(arraylistlabel.Text) Then
 arrayListContactGroup.Remove(arraylistlabel.Text)
End If
End If
Next
ViewState("ArrayList") = arrayListContactGroup
-------------------
Public Sub setSelected()
Dim arrayListContactGroup As New ArrayList
If ViewState("ArrayList") IsNot Nothing Then
arrayListContactGroup = CType(ViewState("ArrayList"), ArrayList)
End If
For Each row As GridViewRow In gridview1.Rows
Dim chkselectcontacts As CheckBox = CType(row.FindControl("chksel"), CheckBox)Dim arraylistlabel As Label = CType(row.FindControl("contid"), Label)
If arrayListContactGroup.Contains(arraylistlabel.Text) Then
chkselectcontacts.Checked = True
Else
chkselectcontacts.Checked = False
End If
Next
End Sub
--------------------------
Protected Sub Selcon_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Selcon.SelectedIndexChanged
getselected()
databind1(ViewState("sort"), ViewState("ascdesc"))
setSelected()
End Sub
My problem is,arraylist values(checkbox values) stored in viewstate,viewstate get the values no problem,but whenever i go to dropdown list select index change at that time we want add viewstate values and current checked checkbox values,but its doing opposite side operation i mean removing the view state value.see i can underlined that line.

I didnt get it.whn i tried i get the first location tags roles.also i tried to change the second location tags path by selecting the values .but in this case also it will be displayed in the first location tag.what is the reason i will attach the code with it.
string path = Server.MapPath("web.config");
string pageset = DropDownList2.SelectedItem.ToString();
XmlDocument xDoc = new XmlDocument();
xDoc.Load(path);
XmlNodeList nodeList = xDoc.GetElementsByTagName("location");
XmlNodeList nodeAppSettings = nodeList[0].ChildNodes;//Getting All The Location Tags
XmlNode nodeAuthorization = nodeAppSettings[0].ChildNodes[0];
XmlNode nodeAllow = nodeAuthorization.ChildNodes[0];
XmlAttribute XmlAttRoles = nodeAllow.Attributes[0];
XmlAttribute pageattr = nodeList[0].Attributes[0];
for (int i = 0; i < LocPath.Items.Count; i++)
{
if (LocPath.Items[i].Selected == true)
{
pageattr.InnerXml = pageset;
xDoc.Save(path); // saves the web.
}
}
Th LocPath is the dropdownlist that displays the page attribute .from there i select the 2 location tag path and select the changable value from the DropDownList2.whn i click the button event the path will be displayed in the first location tag.....why .plz help its urgent so i ask to u people.

You need to write AJAX code and call it on keyup event for textbox. Create a div element on fly and show the results there. It will look like a autocomplete. If you are not at all familiar to write AJAX code check this[^] to get a starting,

hi
i want to compare date using compare validator .and date format must be mm/dd/yyyy .how to set that??
Jintal Patel

Hi..
for your requirement ..
Regular Expression VAlidator is suitable...
Since u dont compare for a particular date... Compare Validator doesnt comes in to the picture...
use Regular Expression validator specifying the format for mm//dd/yyyy
Aswini

hi u can set the properties of the compare validator.
just go properties-type-date. By default the date is compared in mm/dd/yyyy format.
Happy programming...
any problem..just ask

hi,
In a simple way, we can say like this...
Consider that your website is a database interactive application.so, you web site application will have code for displaying the data in the page and also for retriving the data from the databse. if you did the coding of retrival from DB and displaying it in UI in the code behind page, you are following single tier architecture. suppose if your DB retrival is a separate class or project consists of generic DB interaction class without depending on the Application context then it is two tier architecture. Means you DB layer is separate from UI layer, two components.
if you still separate the Business Layer then 3 tier architecture, that is the DB Layer as earlier and separting the UI as entity object being used in UI like for example Class Employee with business logic and Employee object is being used in UI layer(code behind file) then three tier architecture, having DB layer for DB interactions and Business Layer as Employee and third part is code behind file.
still we can proceed like this by using COM and web services. these are N tier architectures.
Cheers
