My client does not want to see ClientID, AgentID, etc., but I need those id's in order to update the database from the control. How do I hide them from the client and still use them in the query?
View 16 RepliesI have a GridView that is successfully populated by an IList. IThere are about 2 dozen columns I only need 8. I am trying to call:
this.grdView.Columns[0].Visible = false;
But I get an index out of range error. And when I call, this.grdView.Columns.Count I get 0.
I have tried this on several events including: grdView_RowDataBound
I am using Visual Studio 2005. I have a gridview and when it is in edit mode, there is a locked textbox and an associated dropdownlist for the signature field. If a name already exists in the database, it will show up in the textbox. In that case, I would like to hide the dropdownlist.
So far, I have not been able to figure out how to make this happen.
My latest attempt is this:
Protected Sub GridView1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing meString = (CType(GridView1.Rows(e.NewEditIndex).Cells(2).FindControl("meSigLabel"), Label)).Text Dim meDDL As DropDownList = CType(GridView1.Rows(e.NewEditIndex).Cells(2).FindControl("edMESigDropDownList"), DropDownList) If meString <> String.Empty Then meDDL.Visible = False Else meDDL.Visible = True End If End SubI receive a NullReferenceError. During debugging, the mestring variable has a value but the meDDL is Nothing.What am I doing wrong?

<tr><th></th></tr>. I don't know why the header row don't disappear.

I have developed a gridview that groups rows together based upon a field in the gridview. To separate each group, I have inserted a row that contains the name of the group.
However, I have hit a problem, what I need to do is to have an image button on the row I have inserted between the groups, which when clicked will hide and show the rows in that group in a toggle fashion. I can get the start of the row for a group, but I am unable to work the number of rows in a group and to then show and hide the rows in that group.
how can i hide a selected row using checkbox item template?

datasource could be .1
coulmn: id-value1-value2-value3
row: 1-4-3-NULL (output: hides row value3) because the value is NULL
.2
coulmn: id-value1-value2-value3
row: 1-4-NULL-NULL (output: hides row value2,value3)

I've programatically created a DataView item by adding columns and rows to a table in the class file. Then I add that to my webform using a GridView. I'd like to hide some of the columns so that the end user doesn't see them but still be able to access their values.
How do I do this programatically? The table.Columns.Count returns the actually number of columns. Somehow when it converts into a DataView, it is only returning 1 column.
//From class file
[Code]....
//From webform
[Code]....
In this example, I want to hide the ID column.
I want to hide the select button in my grid view programmaticlly in the form startup. how to do this?

In my aspx page, I have a formview and a gridview. I am using the insert template of the form to insert an application number and applicant name both of which the user will enter.
I have a insert stored procedure that checks if that same number exist, it won't enter one, if not it will. ID of that table is autoincrement.
If a new number entered, it should show in the gridview as in my query I am asking to show the max ID. The applicatin number in the grid is a hyperlink which allows the user to go to a details page.
My problem: Whenever I click the save button in the formview, the grid becomes visible with the last created number. It is ok if the system allow to enter a new record. But if the number is a duplicate and the system does not enter a new number, still the grid shows with the last created number.
How can I implement what I want to do.
The stored procedure is:
ALTER PROCEDURE [dbo].[InsertNewChurchApp]nvarchar(6),
@AddBy
@Applicant nvarchar(80),
@PK_ApplNo nvarchar(19),
[Code]....
I have a gridview which displays a list of submittted applications with a column that contains an edit link.
<asp:TemplateField HeaderText="Status">
<ItemTemplate>
<asp:LinkButton ID="lnkBtnEdit" runat="server" CommandArgument = '<%# Eval("appID")%>' Text = "Edit" OnClick = "editApp" />
</ItemTemplate>
</asp:TemplateField>
I want to hide the link button if the status (value 1 or 0) of the form is set to 1. Here is the code I am trying to use.
Protected Sub gv1_RowDataBound(sender As Object, e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
'get the cell cell value
Dim status As Integer
[code]....
I think my mistake lies in getting the status value (as it ouputs 0 for every application).
On a page of my project, i have a gridview, i need to perform following operations with it:
1. On Page_Load i want to bind all the data (100 Rows) with the gridview.
2. On my Page i want to show only 4 records with Show More/Show Less Links.
3. When user clicks on the link, i want to show All data or 4 Rows accoeding to the link.
4. I don't want any roundTrip to the server, so plz don't suggest AJAX, i want to attain this by using Javascript.
I have a webpage that lists information about trucks and their map sections and whether the combination is active and will be used.
On the page I put a check box that says Show Only Active and marked the checked property as true by default. When the RowDataBound event fires I check to see if that checkbox is marked as true and if it is I check if the individual map sections are marked as active. If they are not active then I set the row visibility equal to false like below.
[code]....
dv = new DataView(table);
Table.Columns.Add("ID", typeof(string));
table.Columns.Add("Type", typeof(string));
table.Columns.Add("EmpName", typeof(string));
table.Columns.Add("Manager", typeof(string));
row = table.Rows.Add();
row["ID"] = result["ID"].ToString();
row["Type"] = result["Type"].ToString();
row["EmpName"] = result["EmpName"].ToString();
row["Manager"] = result["Manager"].ToString();
Then I am adding boundfield to gridview for all 4 columns. Now I want to check if "Type" column contain "Sales" thne do not show "Manager" columns. Let me know can I do this?
