I have a gridview that I am dynamically creating and populating.
GridView myGrid = new GridView();
myGrid.Showfooter = true;
myGrid.Columns.Add(new BoundField() { HeaderText = "Serial #", DataField = "serial_number" });
...
...
...
myGrid.DataSource = myDS;
myGrid.DataBind();
My problem is that I'm having problems figuring out how to add a templatecolumn with a dropdownlist in it.
my c# web app containing a gridview template field with one column as dropdownlist,drop down list contains 3 items such as disposed,fitted to,battery room,when i click edit button corresponding row is selcted bt dropdown list contain its first value ie disposed instead of actual values in database, i used the following code for retrieving values from dropdown during updation
DropDownList tb3 = (DropDownList )GridView1.Rows[e.RowIndex].FindControl("drpstat")
;
my html code for my gridview is :-
[Code]....
Below is the gridview with 3 columns and column 1 has panel scrollbar for each item/row:

View 2 Repliesi am kind of new in the .net world. I would like to know how you can add a link column with an image to a datagriid.
P.S. i am using Visual studio 2005.
I have set the Datasource of my gridview in code behind and created no columns (All columns in gridview are created automatically). Then I added a template column in gridview. Now I want to change the order of my Templated column in gridview at runtime. I want to show the templatedcolumn at column 20 but it is shown as first column. My Grdiview looks like this:
<asp:GridView ID="grdForecast" runat="server">
<Columns>
<asp:TemplateField></asp:TemplateField>
</Columns>
how can I set the template column at specified place(in my case it is column no. 20) and I've set Datasource and Databind the gridview in code behind at page load.

i want to sort my Gridview rows by a template column that is not bound to any database field. This template coulmn just has a label whose text i set in code depending on a value in a different column that is databound. So am stuck on how to set its sortExpression since its not linked to an column.
View 1 RepliesI have created a gridview dynamically from scratch and added it to my aspx page. This works fine, but i have a button in the footer of on of the columns, which when clicked on makes the gridview disappear and doesn't fire the onclick event that it should. This should obviously not be the case. My question is why does the event not fire and why does the gridview vanish? Bear in mind i have never created aa gridview in the code behind before, so excuse me if i am being dense

I have data on SQL server like this:ItemID QuantityI would like to display that data in GridView using templates. The thing is that instead of Quantity in numbers I would like to display text:Green text saying "item on stock" when Quantity > 0Red text saying "item unavailable" when Quantity = 0My question is, how should I implement such functionality? How to generate such HTML tag dynamically and add it to the template?
View 1 RepliesI 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?
regarding gridview Template column.in my template column i have a textbox and i need to invisible to user. but when i set visible property "false" then textbox value is not render.

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 am using Asp.net with C#.
I have one gridivew, which is showing 20 records. And also, in item template of Gridview, I used one dropdownlist. It means there are 20 dropdownlist with all the 20 rows. That dropdownlist is already binded, means showing the records/items - 8 items. No issue with this.
Now, what I want is, when ever, I select any item from the drodownlist against each row in that gridview and click on the button "Save", it will save the id of all row with all the values of dropdownlist.
The above is my gridview item template, I have used this javascript for row total

gridview row databound code behind
[Code]....
The above code is getting row calaculated on key up. With the same code in need column total also. I need total of column quantity and total in their respective footer textbox.
I am trying to have different options for different user roles. Here is my code:

I am trying to bind dropdownlist in Gridview under EditItemTemplate under RowBound event. But it gives me blank rows in the drop down list.Here is my DesignÂ
<asp:TemplateField HeaderText="Description">
<ItemTemplate>
<asp:Label ID="lblDescription" runat="server" Text='<%# Bind("Description") %>' Width="400px"></asp:Label></ItemTemplate>
[code]....
I see the dropdown but the dropdown is blank, but there are rows in the database for this column and in the footer row it is working fine.
I edited my gridview template by adding an additional column of checkbox and to its header
I managed to do a checkchange for select all or none and for selecting single of multiple checkbox.
My problem here is that when I try to select all, uncheck another checkbox, the header checkbox is still checked and the unchecked checkbox becomes checked again.
If i did not check my header checkbox and just check it normally, its fine.
I have written some code to dynamically generate template columns for gridview which works well. However, each cell in the gridview has to be a linkbutton, which when clicked does a db update and redirects to a specific url with some parameters in it.
I have attached a click event handler to the linkbutton in the InstantiateIn method but the event does not seem to fire.

How to display the selected value of a dropdownlist in header taemplate of a gridview? As i change the dropdownlist's value, it should also change in the gridview. i have taken a label in the gridview's header template named "lbl_mnth" my dropdownlist's id is "ddl_mnth".

I have seen code for adding columns at runtime but here is another scenario for you. I am using a SQLDatasource control for my gridview. And the data returned can have different columns based on the filter meaning one time I may have a column A1, A2, A3 and another time I may have A2, A3, A4. Is there any way I can look at the columns when it is binded at the beginning and add the columns first?
I really need to use the SQLDatasource though because I am connecting to an AS400 and it is using a connection already made in the webconfig and do not know any other way. I do if it was MSSQL server but not this.
I'm having an issue with trying to add a button to my grid. My GridView is first loaded with data in the PageLoad event.
I'm then taking the data in the first cell of each row, and creating a button that will link to a URL. To get the URL, I have to run a query with the data in the first cell as a parameter. I was doing this in the RowDataBound event at first, but hitting that query for every row was making it really slow.
So I decided to add a button that would retrieve the URL only when you clicked the button.
Here's my GridView:
[Code]....
The grid generates fine, the button gets added to the grid for each row. But when I click on it, the RowCommand event doesn't fire, and the page just refreshes.
