Windows desktop applications and Web applications are totally different and you cannot mix them together. If you are developing a system that will be used by remote clients then you will need to create a web application: start at the ASP.NET web site for tutorials and samples[^].

Use the best guess

Web applications are deployed on internet.
Windows applications are generally downloaded from internet on system to work stand alone without need of network.

Windows Form / Windows Application and Desktop Application are those application which run in windows operating system in desktop mode not in web mode having different structure than web and hence they are run through executable and after publishing your source code you can upload it to live server.
Desktop Application create through File => New project in Visual Studio .net and chose the language in which you want to develop most widely used are C# and VB .
The Best backend database for application is Microsoft SQL Server.But depend on Requirement you use oracle, mysql or attach any other oledb.

Dataset

I have a dataset returning the following values:

Name	Region
Tom	1
Dick	3
Harry	3
Paul	2

I need to display each of them in different panels
for e.g. in panel for region 2 i need to display only Paul
in region 3 display Dick and harry
and display Tom in the panel for region 1.

Any idea how to do this?

I can create 3 different queries for each panel but i want to avoid that repetition.

You can use a repeater with gridview inside of the repeater's ItemTemplate and bind the gridview in the ItemDateBound Event of the repeater.

Hi,

actually I have bounded a dropdownlist in gridview in edit mode, but the problem is that whenever i try to select another value from dropdownlist, it auto select the first value.

I also used !IsPostBack property on page_load event but still it is not selecting the another items.

<pre lang="c#">
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if ((e.Row.RowState & DataControlRowState.Edit) > 0)
{

DropDownList ddlCost_Code = DropDownList)e.Row.FindControl("ddlCost_Code");

BAL bl = new BAL();
DataTable dt_for_CostCode = null;

dt_for_CostCode = bl.Select_Cost_Code();
if (dt_for_CostCode.Rows.Count > 0)
{
ddlCost_Code.DataSource = dt_for_CostCode;
ddlCost_Code.DataTextField = "Cost_Code";
ddlCost_Code.DataValueField = "Proposalno";
ddlCost_Code.DataBind();
}

}

if (!IsPostBack)
{

try
{

Log_Booked_Info_Through_Booking_Table();

}
catch (Exception ex)
{
WebMsgBox.Show(ex.Message);
}
}

}
</pre>

Ofcourse, it will select the first item, since you are just binding the dropdownlist, i do not see the code line which is making the particular item as selected. i mean, if you wanted to make 2nd item to selected then you could have written as below.

ddlCost_Code.DataSource = dt_for_CostCode;
ddlCost_Code.DataTextField = "Cost_Code";
ddlCost_Code.DataValueField = "Proposalno";
ddlCost_Code.DataBind();
ddlCost_Code.Items[2].Selected = true;

if you do not specify item to be selected, it will select the first item by default.

update the edit template as below.

ASP.NET

<asp:TemplateField HeaderText="Cost Code">
    <EditItemTemplate>
        <asp:DropDownList ID="ddlCost_Code" runat="server"   AutoPostBack="true"        
        onselectedindexchanged="ddlCost_Code_SelectedIndexChanged"
        AppendDataBoundItems="True">        
        <asp:ListItem Value="0">-Select-</asp:ListItem>        
        </asp:DropDownList>
        
        <asp:Label ID="lblCostCode_Hd" visible="false" runat="server" Text='<%# Bind("Cost_Code") %>'></asp:Label>
    
    </EditItemTemplate>
    <ItemTemplate>
        <asp:Label ID="Label6" runat="server" Text='<%# Bind("Cost_Code") %>'></asp:Label>
    </ItemTemplate>
</asp:TemplateField>

take one hidden label "lblCostCode_Hd" which hold the selected Cost Code. and in row databound add below code.

ddlCost_Code.DataSource = dt_for_CostCode;
ddlCost_Code.DataTextField = "Cost_Code";
ddlCost_Code.DataValueField = "Proposalno";
ddlCost_Code.DataBind();

Label lbl = (Label)e.Row.FindControl("lblCostCode_Hd");
if(lbl != null)
{
    ddlCost_Code.Items.FindByText(lbl.Text).Selected = true;
}

so, this will select the particular code which you have selected.

hope it works.

I need selectedindexcahged event for some work, without AutoPostBack = true it is not possible.
So I need to keep this property to true. By the way I tried by making it false but the same result I got, it didn't give the solution

Karthik Harve3-Mar-13 23:38

Re: dropdownlist auto select first value in gridview with edit mode

3-Mar-13 23:38

check in any of the events you are rebinding the grid again ?, because rebinding the grid will make the dropdownlist to select the previous value.

Re: dropdownlist auto select first value in gridview with edit mode

after selecting an item from ddlCost_Code selectedindexchaged fires then the whole page posbacks and I am binding the grid on page_load event.

Karthik Harve3-Mar-13 23:59

Re: dropdownlist auto select first value in gridview with edit mode

3-Mar-13 23:59

So, Since you are re-binding the grid, Row_databound is firing, and dropdownlist is also re-binding and the default value is selecting. so, handle the dropdownlist selected index changed evnet, but do not rebind the grid, or else, before binding check the edit index whether edit index is equal to -1 or not. if EditIndex = -1, then bind the grid, otherwise leave as it is.
