Forms Data Controls :: View State And GridView With Template Column
Mar 2, 2011
I have a GridView that isn't databound until the user clicks a button...
The GridView has one bound column: the employee name. It also has a template field that has an empty asp:Table.
I populate the tblInfo in the RowDataBound event.
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 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?
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)
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.
I have created a property called as IsEntryGrid. Which is boolean. If it is true then it is assumed that it will be a grid where dataentry is possible from footer controls. Controls in footer are created dynamically. My problem is that when i m pressing ok image button control state is not maintained.
eg. In my footer say there is a text box for field OrganicationCode. I enter Org Code as M01 and if i press enter, i m not getting that back in my page event..
I have a gridview in which I have the autopaging option set to true, when i load the grid everything works on the first page, i can even go to second page , but when i click the edit button nothing happens and after that any click blows up the page giving me error Faile to load view state.
I have a grid view with a few columns, for example a column in the grid view contains description of a product. The description might be very long, so i want to display only first 100 characters of the description and then provide a . when we click on the. then the whole description should be displayed.
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.

I am trying to create a datagrid with bound columns and template columns at runtime. I can successfully create the grid and columns if I only put one control per column, however, I have a need to place two controls in a single template column. If I create the column and controls at design time, it works fine as such:
My issue is trying to place both that label and dropdownlist into the same template column at runtime. Using code as follows, I can get one or the other successfully into the grid at runtime, but not both: [Code]....
How can I add a second (ItemTemplate?) to that TemplateColumn? I tried: [Code]....
but then only the dropdown list (the EditItem) shows in the grid at runtime.
I have set the Datasource of my gridview in code behind and created no columns. 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:
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.
