I bound the gridview having some fields(ID, StudName, City) Â and Display Button. When I click on the Disply button I approve the student and updation will happen.Â
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... Â next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :Â
<%# Container.DataItemIndex+1 %>
and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?Â
I have a ASP.NET/C# web application that contains user controls with GridView controls. The GridView controls contain the following column types.
CommandField - Contains buttons like Edit, Select, Delete, ...
BoundField (x8) - Contains the data fields from the database.
TemplateField - Contains a single ASP:Menu control.
The menu control consists of the following structure.
Navigate To (Parent MenuItem)
- Location A (Child MenuItems)
- Location B
- Location C
- Location D
- Location E
What I need to do is when the OnMenuItemClick event is fired, determine which menu item was clicked (already done) and then capture what the value in the first BoundField cell is for the row that the menu item was clicked on.
So, for instance if I have three rows in the grid with the first BoundField column containing the IDs 1, 2 & 3. Then I hover my mouse over the menu on the 2nd row, and click the menu item "Location C". The "Menu1_OnMenuItemClick" event is fired and I can determine that "Location C" was clicked by e.Item.Value == "Location C".
However, how do I navigate up through the API to determine what the contents of the cell in the first bound field column are for the row that was clicked on?
I have a GridView that isn't databound until the user clicks a button...
[Code]....
The GridView has one bound column: the employee name. It also has a template field that has an empty asp:Table.
[Code]....
I populate the tblInfo in the RowDataBound event.
[Code]....
The CreateInfoTable(...) method manually creates the rows and columns for the employee. This works, and I can see my dynamically created table; however, after the user submits the form back to the server for PostBack, the rendered page after submission is missing my manually populated table. How can I save my table across PostBacks?
I have a gridview control
i add template column dynamically to gridview
like this in a function in AddColumns button clickevent
gv.Columns.Clear()
Dim chkCol As New TemplateField
chkCol.ItemStyle.Width = 20
chkCol.ItemStyle.HorizontalAlign = HorizontalAlign.Center
gv.Columns.Add(chkCol)
2)
and in row databound event i added checkbox control to this template field. like this
Protected Sub gv_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
Dim chkbox As New CheckBox
chkbox.ID = "chkSelect"
e.Row.Cells(0).Controls.Add(chkbox)
End If
End Sub
HERE I WANT TO GET CHEKC BOX IN btnok click event
Protected Sub btnOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnOk.Click
Dim linkId As String
Dim summary As String = ""
'Enumerate the GridViewRows
For index As Integer = 0 To Me.gv.Rows.Count - 1
'Programmatically access the CheckBox from the TemplateField
Dim cb As CheckBox = CType(gv.Rows(index).Cells(0).FindControl("chkSelect"), CheckBox)
If cb IsNot Nothing Then
If cb.Checked Then
linkId = Me.gv.DataKeys(index).Value
End If
End If
Next
Me.Page.Title = linkId
End Sub
But here i am not getting Check box even i used find control. how i get checkbox
I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.
There is a submit button on the page as well.(this is not in a template column in the gridview)
what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.
Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.
Below is the gridview with 3 columns and column 1 has panel scrollbar for each item/row:
Column 1 | Column 2 | Column 3
---------------------------------------------------
12345 ↑ | |
14323 | |
43345 | |
45678 | |
↓ | |
-------------------------------------
3333 ↑ | |
32123 | |
544444 | |
99088 | |

How to add  dynamically <asp:panel> scrollbar for the Column1  in the code behind.
I am looking to enable/disable controls (TextBox, DropDownList, etc.) in a GridViews template column based on the users specific access level when the user clicks the edit button. I have tried the following two methods:
[Code]....
I have an ASP.NET GridView control in a Web Form. For the sake of simplicity, I will say that this GridView is defined as follows:
[code]...
When each of these rows is bound (a.k.a. during the "myGridView_RowBound" event), I want to get the ID, Name, and Age values. My problem is, I cannot figure out how to get the "ID" value. The reason why is because it is in an invisible field.
How do I make a column invisible in a gridview? I tried to use this:
dataGridView.Columns(0).Visible = False
But its getting an error "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index". How can I do this?
I have a grid view which is dynamically generated via C# using a DataSet. I'm passing a row ID field (from the database) to the grid view, as this is required when a user clicks to edit a records. However I don't want the user to be able to view the column.I have tried the following but it doesn't seem to work? hide the column or a better way of attaching the information to the grid view row so it can be used at a later stage. c#
DataColumn ColImplantCustomerDetailsID = new DataColumn();
ColImplantCustomerDetailsID.ColumnName = "Implant ID";
ColImplantCustomerDetailsID.DataType = typeof(int);
ColImplantCustomerDetailsID.Visable = false; <-- visable doens't work here.

How do I pass a GridView column value to the code behind with out making it visible? In the following code, I would like to capture the ContactID with out making it visible in the GridView.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1"
OnRowCommand="_OnRowCommand"
>
<Columns>
<asp:BoundField DataField="ContactID" HeaderText="ContactID"
SortExpression="ContactID" InsertVisible="False" ReadOnly="True" />
.....other columns in the grid....
<asp:ButtonField ButtonType=Button CommandName="Remove" Text="Remove" />
</Columns>
</asp:GridView>
I would like to capture ContactID as follows. I can not do so with out making it visible = true in the GridView.
if (e.CommandName.Equals("Remove"))
{
int index = Convert.ToInt32(e.CommandArgument);
int ContactID = Convert.ToInt32(GridView1.Rows[index].Cells[0].Text.Trim());
}
Dim Application = From AL In db.AnnualLeave _
Where AL.Approval <> True _
Select LeaveID, EmpID, Name
GridView3.DataSource = Application
GridView3.DataBind()
after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. i found a thread about similar problem here [URL] Note that the Gridview columns have NOT been defined at design time.
I have an accessdatasource that pulls several columns from my users table including [userID]. Then I have a gridview that displays all this information by autofilling the columns. Finally I have added a column that I want to link to viewUser.aspx?userID=####. The #### would of course be from the query.
Here's my column that I've added:
<Columns>
<asp:HyperlinkField datatextfield="View User"
datanavigateurlfields="userID"
datanavigateurlformatstring="viewUser.aspx?userID={0}"
headertext="Link"
target="_blank" />
</Columns>
This is my first time using this so I'm not sure what's wrong. I don't understand the '{0}' part and that's also where the problem lies. On the viewUser page when I print the querystring("userID") it just shows {0} as expected. How do I get my userID in there?
I list selections of available items in a gridview and have added a button column for adding items to a cart. Is there a way to add a column where the user can enter the quantity to add?
View 1 Replieslet me explain completly. I designed an gridview, header template i added one textbox and button if the user enter something on Txtbox and click button then based on input i show corresponding rows only, all other rowss will be hidded using Javascript like below
tblOrders.rows[CurrRow].style.display = 'none';
now im doing something on the Gridview_RowCommand event at this time the gridview got refreshed so that the hiden rows are visible, but i dont want to show the hidden(invisible) rows while rowcommand event fired.
I have a gridview that is being populated off of a query that has joins in it. It works fine. However, I want to display one record of all information but then blank out all colunmns accept 1 for the other 3 records that it is picking up. In other words, right now, all three records have duplicate info in them accept this one column. can this be done? Can I somehow blank out other columns based upon what is in the single column? This is all being done in a gridview. I realize it would do a master detail type scenario but I want all of this information to display without someone having to click on a field or anything.
View 4 RepliesI've run into this before, but I was using a formsview and just changed the field to hidden. I am trying to get the value of a cell out of a gridview to a variable and here is the code:
[Code]....
This works perfectly if column 6 is visible, but because it's an id number (which is not the primary key) I do not want it visible, but changing it to visible="false" causes this code to return null. Changing it back to visible and it works.
I'm not sure why the visiblity of a control changes the functionality of it.
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
View 3 RepliesI have a Gridview with some template columns. Inside one of the columns, I have a ImageButton with a serverSide OnClick handler to show or hide a panel. And all the panels by default are hidden. What happens is that when I click the imageButton the first time the panel gets displayed, but if I click the same button, on the same row again, - where the panel is now visible - the panel doesn't hide itself. Here's what happens when the imageButton is clicked:
protected
void ImageButton1_Click(object sender,
ImageClickEventArgs e)
{
ImageButton imgBt = (ImageButton)sender;
Panel compRecDetails = (Panel)imgBt.NamingContainer.FindControl("CompanyRecDetailsPanel");
if (compRecDetails.Visible ==
false)
compRecDetails = true;
else
if (compRecDetails.Visible ==
true)...............................
I am trying to hide the first column of my gridview, a template/command column.
