Forms Data Controls :: Get GridView Cell Value From MenuItem In Template Column?
Jul 14, 2010
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 Formview residing inside am Item Template of a Gridview. The formview is not populating, and I am pretty convinced that I am not passing the parameter properly from the Gridview to the Formview. I have listed the relevant code only, so that you can scan though it easierGridview tag:
However the the column in the gridview is dynamic created which might more or less depend on system logic.
I have try to set the column width in row_created event, rowDataBound event, but it show me that no column is available by using gridview.columns.count.
I have an ASP.NET/C# web application that has a GridView control. In the last column of that GridView control I have a template field that contains a menu. In the OnMenuItemClick event I get a reference to which row the event was fired from, in order to determine what value the ID field contains for the current row. Currently I reference this cell by it's index "gvr.Cells[1].Text". However, this is highly volatile since any changes to the location of the ID column breaks the code. How can I instead gain the value in the cell that has a column name (or some other name-like property) of "SomeID" from a GridViewRow reference?
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?
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.
I have a grid view populated with some data included bit fields and I made an export to excel function For each row i need to check the cell with the bit value to change the cell color, but the cell is always empty, even if is the field is set to False or True. foreach (GridViewRow row in gv.Rows)
I'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
I developed the grid view in which i define 2 columns(Common Name, Common ID). I wanted that when i edit particular cell of grid; if i select any cell of column "Common Name" then it tells the name of particular column name and when i click on any cell of column "Column ID", it shows that column name.
I have a GridView, in which the width of each column is dynamic and changes depending on the dataset. I need to get the width of each column for use in my PDF exporter, but the column/cells width is always '0', presumably because I haven't set the width property.
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 hide the first column of my gridview, a template/command column.
I want to export my gridview to Excel and the teplated contol shows up in the Excel file as a column.
This is what I tried in code :
Me.GridView1.Rows.Item(0).Visible = False - This doesn't work ! Me.GridView1.AllowPaging = False Me.GridView1.AllowSorting = False Me.GridView1.EditIndex = -1 Me.DataBind() Response.Clear() Response.ContentType = "application/vnd.xls" Response.AddHeader("content-disposition", "attachment;filename=SearchedItems.xls") Response.Charset = " " Dim swriter As New StringWriter() Dim hwriter As New HtmlTextWriter(swriter)

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:
[Code]....
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.
