Forms Data Controls :: Dynamically Populated Dropdownlist Inside Gridview

Mar 28, 2011

I have a gridview which contains a templatefield. Inside this is an ImageButton and a dropdownlist. This is all created in the aspx page, although the ddl list items are populated in the RowDataBound event in the vb page. When i change the selected item in the drop down list and hit the imagebutton, the selected item is not maintained after postback. Instead the first record is displayed in the dropdownlist. I have wrapped an If Not Page.IsPostback around the datasource and databind's but this doesn't help. I have tried enabling viewstate in all areas on the page too, but still nothing. The list items for the ddl must be created on RowDataBound also. As far as I am aware, my ddl is not really dynamic, its just the list items which I add in the code behind which are classed as dynamic.

Forms Data Controls :: Passing Populated Search Values In A Gridview To Another Page Using Querystring Or Sessions

Nov 8, 2010

We do have a search page for customers which returns a list of data from a table.

Once we select on an item it should redirect to another page with customerId as a querystring parameter..

Now the problem is we have to save all the customerIds and need to send them to display page..and need to select next one once they done with previous one without going to the search page again..

Example:

if they got 10 customers in the search page then we need to send all 10 ids to display page by starting display of firstone and once they select next button on display page they have to move on to the next cutomer from that list..if they reached the end of list they have to start again from the first...we need to avoid the user going to the search page for each customer every time...

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>
</asp:SqlDataSource>
</ItemTemplate>
</asp:templateField>
</Columns>
</asp:GridView>

Gridview SQL Parameter Null From Javascript / Ajax Populated Dropdownlist

Sep 7, 2010

My issue is similar to [URL] how-to-use-the-value-of-a-selected-value-from-a-dropdownlist-populated-with-ajax but I am using ASP.NET, not PHP. I have a dropdownlist that is populated by another dropdownlist's current value through ajax. So if DDL A is 'NY', DDL B is populated with different data relating to 'NY'. I need that data to be posted back to the server because this affects an SQLDataSource parameter. However, as far as I can tell, the value is always null after postback resulting in the gridview to be empty.

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.

Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file

So far the only tutorials I've encountered are ones the have the database bound through design view and gridviews with only one column that can be added. In my particular example I have multiple columns that need to be added and I have already bound the data to the gridview.

Forms Data Controls :: Update Multiple Database Fields From A DropDownList In A GridView?

Oct 20, 2010

I have a GridView with a DropDownList in it bound to the [Applicants] table in SQL Server 2005.

The DropDownList Items Text and Value come from SqlDataSource3, "SELECT VoucherType, VoucherNumber FROM [Vouchers]"

I need to send the DDLs selected Text to [Applicants].[VoucherTypeIssued] and the Value to [Applicants]. VoucherNumber]

I already have a "dlVoucherTypeIssued_SelectedIndexChanged" event in the code behind to put "Voucher Issued" into [dbo].[Vouchers].[VoucherStatus]. I'm having trouble getting all three values written to the database at the same time.
