View 2 Replieshow can I use a "where clause" in the below stored procedure to retrieve columns and display in gridview? I have three textboxes on the form. One is for user to enter "regno" to retrieve record for a particular students, the remaining two textboxes are for "from date" and "to date" respectively so that user can select from date and to date from two calendar controls I have on the form. On selection date appears in the two textboxes so that records can be retrieved based on the selected date.

I have a grid view will two different button columns. I want to perform a different action depending on what button the user presses. How in the SelectedIndexChanged event do I determine what colmun was pressed. This is the code I use to generate the columns.
grdAttachments.Columns.Clear();
ButtonField bfSelect = new ButtonField();
bfSelect.HeaderText = "View";
bfSelect.ButtonType = ButtonType.Link;
bfSelect.CommandName = "Select";
bfSelect.Text = "View";
ButtonField bfLink = new ButtonField();
bfLink.HeaderText = "Link/Unlink";
bfLink.ButtonType = ButtonType.Link;
bfLink.CommandName = "Select";
bfLink.Text = "Link";
grdAttachments.Columns.Add(bfSelect);
grdAttachments.Columns.Add(bfLink);
My GridView uses auto generate Edit & Delete command button. And then program the insert button. I want to do something when users click the Edit button so I wrote something like this:

View 2 RepliesHere's my radiobuttonlist:
<asp:RadioButtonList ID="Pending" runat="server" AutoPostBack="True" OnSelectedIndexChanged="Populategrid">
<asp:ListItem Value="250">Over 250</asp:ListItem>
<asp:ListItem Value="300">Over 300</asp:ListItem>
<asp:ListItem Value="350">Over 350</asp:ListItem>
<asp:ListItem Value="400">Over 400</asp:ListItem>
</asp:RadioButtonList>
I have a gridview set up to bring in all of the items listed in the radiobuttonlist. When the page loads the first time it comes in as showing Over 250 only:
Private Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
GridView1.Columns(2).Visible = False
GridView1.Columns(3).Visible = False
GridView1.Columns(4).Visible = False End Sub
This is the code behind:
Protected Sub PopulateGrid(ByVal sender As Object, ByVal e As EventArgs)
'Select Case Pending.SelectedItem.Value ' Case "300"
Dim conn As New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("PendingClaimsConnectionString").ConnectionString)
Dim cmd As New Data.SqlClient.SqlCommand
[code]...
I'm getting an error under the If pending.selected value = "300" and .Parameters.AddWithValue etc...saying operator AND is not defined for types Boolean
Private Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
GridView1.Columns(2).Visible = False
GridView1.Columns(3).Visible = False
GridView1.Columns(4).Visible = False End Sub0

View 2 RepliesI have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"
protected void BuildColumns()
{
// The first column to begin to insert the columns in the GridView
int columnIndex = 5;
BoundField aoColumn = new BoundField();
aoColumn.HeaderText = "New Column 1";
gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback
gvMyGrid.Columns.Add(aoColumn); // works fine
columnIndex++;
foreach (MyEntity my in _myEntityCollection)
{
BoundField myColumn = new BoundField();
myColumn.HeaderText = String.Format("{0:d}", my.StartDate);
gvMyGrid.Columns.Insert(columnIndex, myColumn);
columnIndex++;
}
}
I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.

I have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?
