Below is my current codes which I have a problem.

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)

SqlDataAdapter adapSel;
string mySQL = "SELECT '" + dd_list.SelectedValue+ "' FROM examtimetable ";

Forms Data Controls :: How To Add Lookup Table Values To A DropDownList And Bind To A FKValue In The Grid

Jan 26, 2011

I have a GridView control that has a SQLDataSource.

The GridView provides me with a list of musical artists (from the tblArtists)

In the Grid, I have a field, FKGenreID, that is a Foreign Key value for music Genres.

(An example of the data in that field would be "7", which upon lookup would mean Classical in the
tblGenreList table.)

What I'd like to do is add a DropDownList control that looks up the tblGenreList table and populates the DropDownList with the ID and Description from the tblGenreList Lookup table.

Now the tricky part is that if the GridView field (FKGenreID) has a value, then I'd like the corresponding Genre Description to be displayed in the DropDownList

Alternately, if there is no value for FKGenreID in the GridView, then I'd like the DropDownList to show that nothing was selected, but have the list of Genres available.

Most importantly here, when the user makes a selection, I'd like the GenreID (from the DropDownList) to be entered into the FKGenreID field in the GridView field.

My thought is that a gridview record may or may not have a value in the FKGenreID field. Either way, the DropDownList is bound to that field. The DropDownList would display a list ofGenre Descriptions for the user to select from. Upon selection, the GenreID column of the DropDownList becomes the value in for the FKGenreID field in the GridView.

Is this possible?

In case it matters, I'm using ASP.NET 4, Visual Studio 2010, and coding in VB

Data Controls :: Bind DropDownList Selected Items To GridView

With reference to : [URL] ....

No you cannot add a third parameter in the Dictionary. It contain Key Value pair data.But if you want to add third parameter then simply use DataTable and add these in the DataTable row.Name of Builder , Title Of Buidler , Builder ID

So how to acheive that task ? so far i did like this :

public void AddNewCMP(string PersonName , string PersonID , string PersonTitle) {
var dt = new DataTable();
if (ViewState["CMPDataTable"] != null) {
dt = (DataTable)ViewState["CMPDataTable"];

[Code] ....

Now on button click i want to add six drop down values to AddNewRow(value1,value2,value3) method .... how to do that ?

i have followed same steps just but difference is i have a edit imagebutton with commandname="Edit".Also dropdown needs to be binded from different table(directory) and not the table through whicch grid is binded(details).

if (e.Row.RowType == DataControlRowType.DataRow && (e.Row.RowState & DataControlRowState.Edit) == DataControlRowState.Edit && GridView1.EditIndex == e.Row.RowIndex)
{
DropDownList DStatusEdit = (DropDownList)e.Row.FindControl("DStatusEdit");
string query = "select distinct status from directory";
SqlCommand cmd = new SqlCommand(query);
DStatusEdit.DataSource = GetData(cmd);

[CODE]..

the page is running but when i click edit image button the dropdwn shows but no data in dropdown binded it is empty.

My gridview is inside update panel.

How can i achieve this?

Should dropdownlist in my case be binded inside rowcommand and how?

Forms Data Controls :: Bind Data From DataSet (DataTable) To A Selectrow DropDownList In GridView?

Nov 19, 2010

I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).

ASPX CODE

[Code].... C#

When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it

Forms Data Controls :: Change The Values In Dropdownlist In Gridview?

Aug 4, 2010

I got a gridview -CompGrid, having 3 columns - Dept, Employees, Status.

The 'Status' tab need to be edited. So that I put a Dropdownlist as an Itemtemplate and connected the 'DataValueField' as 'Status'.

Now I can edit each row by row only. Some times it needs to update all the employees status in one department.

So that I placed 2 more dropdownlists in outside of gridview.

1. Department List, 2. Status List.

My requirement is this, When I select one department and corresponding status, it should update all the records of that department in the grid.

Forms Data Controls :: Dropdownlist Won't Display Values In Gridview With Use Of Parameter

Jan 31, 2010

My database has 4 colums;

TraditionalID-------------TraditionalName------------Singles-----------Suppers

Singles and suppers are money fields for the price of same item. A bit like the price of a Small, Medium or Large item. What I would like to do is display the 'Singles' price and 'Suppers' price in seperate listitems so the user can choose 1 of them.

GridView:
Traditional Name__________Size
Chicken-------------------[DROPDOWNLIST]

DropDownList:
Price of Single is: 1.50
Price of Supper is: 2.50

My page loads up with the correct items in TraditionalName colum but the DropDownList is completely empty. I'm aware I don't have anything in for DataValueField and DataTextField but I have tried putting things in these attributes, like Suppers and Singles, but nothing works, so I have taken them out below.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="TraditionalID" DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="TraditionalID" HeaderText="TraditionalID" InsertVisible="False" ReadOnly="True" SortExpression="TraditionalID" Visible="False" />
<asp:BoundField DataField="TraditionalName" HeaderText="Meal" SortExpression="TraditionalName" />
<asp:templateField HeaderText="Size">
<ItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSource2">
</asp:DropDownList>
<asp:HiddenField ID="RowTraditionalName" runat="server" Visible="false" Value='<%# Eval("TraditionalName") %>' />
<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%$ ConnectionStrings:The CodfatherConnectionString %>"
SelectCommand="SELECT Suppers AS Suppers, Singles AS Singles FROM [Traditional] WHERE TraditionalName = @TraditionalName">
<SelectParameters>
ControlParameter Name="TraditionalName" Type="String" ControlID="RowTraditionalName" PropertyName="Value" />
</SelectParameters>

Forms Data Controls :: Maintaining Selected Values In DropDownList While Paging In GridView

Jan 8, 2011

I have a problem with keeping the selected values in DropDownLists in rows in GridView while paging. I have this code behind:

private void RememberOldValues()
{
ArrayList LinijaIDList = new ArrayList();
int index = -1;
foreach (GridViewRow row in GridView1.Rows)
{
index = (int)GridView1.DataKeys[row.RowIndex].Value;
if (Session["equal_ITEMS"] != null)
LinijaIDList = (ArrayList)Session["equal_ITEMS"];
if (row.Cells[0].Text == lineTextBox.Text)
{
if (!LinijaIDList.Contains(index))
LinijaIDList.Add(index);
}
else
LinijaIDList.Remove(index);
}
if (LinijaIDList != null && LinijaIDList.Count > 0)
Session["equal_ITEMS"] = LinijaIDList;
}
protected void Button1_Click(object sender, EventArgs e)
{
//Session["equal_ITEMS"] = null;
RememberOldValues();
GridView1.AllowPaging = false;
BindGrid();
//RePopulateValues();
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("LinijaID", typeof(int)));
dt.Columns.Add(new DataColumn("Ime", typeof(string)));
ArrayList LinijaIDList = (ArrayList)Session["equal_ITEMS"];
//if (LinijaIDList!=null)
//{
foreach (int LinijaID in LinijaIDList)
{
foreach (GridViewRow row in GridView1.Rows)
{
DropDownList Ime = GridView1.FooterRow.FindControl("ImeDropDownList") as DropDownList;
int rowID = (int)GridView1.DataKeys[row.RowIndex].Value;
//string Name = row.Cells[1].Text;
string Name = Ime.SelectedValue;
if (rowID == LinijaID)
{
DataRow dr = dt.NewRow();
dr["LinijaID"] = LinijaID;
dr["Ime"] = Name;
dt.Rows.Add(dr);
}
}
}
GridView1.AllowPaging = true;
Session["equal1"] = dt;
Response.Redirect("CheckedRowsPage1.aspx");
}
// else
//{
// GridView1.AllowPaging = true;
// Session["equal1"]=null;
// }
}

When I insert a value in the TextBox2 and want to select only the rows from the GridView from different pages which have value in the first column the same as the value in the TextBox2, after clicking on Button1 I get this error:

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

VS 2010 - How To Bind Values From Column A In Excel To DropdownList

Apr 7, 2012

How do I bind data from an Excel file named Book1.xlsx in Column A to a dropdownlist? I've tried like this:

Code:
connExcel.Open()
cmdExcel.CommandText = "SELECT distinct BCName From [Sheet1$] where BCName <> '' and ProjectName like 'Total%';"
oda.SelectCommand = cmdExcel
oda.Fill(dt2)
connExcel.Close()
dropdown1.DataSource = dt2
dropdown1.DataBind()

But the dropdown is filled with "System.Data.DataRowView" for all the 5 lines in the dropdown. How do I get the values shown instead of this? It must be some formatting of dt2 I think.
