Web Forms :: GridView With Button On Footer - Error On Button Click To Create New Row
Jan 10, 2014
I am using a web form in vs2010 and in my form am having a gridview with button on footer. I have written the code to create a new row while click the button. If I click the button i got the following error
"unable to cast object of type 'system.web.ui.webcontrols.textbox' to type 'mysite.textbox"....
Below is the button click code.
private void AddNewRow() {
int rowIndex = 0;
if (ViewState["CurrentTable"] != null) {
dtCurrentTable = (DataTable)ViewState["CurrentTable"];
DataRow drCurrentRow = null;
if (dtCurrentTable.Rows.Count > 0)
[Code] ....

I have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit, update and cancel.Gridview will be populated based on the selecteditem of dropdownlist.
if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.

I have used the above grid view in my application ... Its working good, no problem.
Upon clicking the Addnewrowbutton, it uses to create a new row dynamically.
What i need is, new row should also be created dynamically, upon pressing enter key in the last textbox on a particular gird view row. User always can't go and click addnewrowbutton every time to create new row. Instead of it, user can press enter in the last textbox on a particular grid view row to create new row.

How do I do this? Basically, next to the page numbers in the GridView I want a link button to disable paging. This works, but I want the button inside the footer of the GridView, next to the page numbers.

I 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
Code creating columns
Dim gvTownships As New GridView
'COLUMNS
Dim tmpCategory As New TemplateField
tmpCategory.ItemTemplate = New cGridViewTemplate(DataControlRowType.DataRow, "Category")
tmpCategory.HeaderTemplate = New cGridViewTemplate(DataControlRowType.Header, "Category")
tmpCategory.FooterTemplate = New cGridViewTemplate(DataControlRowType.Footer, "Calculation")
'INFORMATION
gvTownships.AutoGenerateColumns = False
gvTownships.ID = cmbChoice.SelectedItem.Text
gvTownships.ShowFooter = True
gvTownships.CssClass = "mGrid"
gvTownships.RowStyle.Wrap = False
gvTownships.HeaderStyle.CssClass = "mgrid"
gvTownships.HeaderStyle.Wrap = True
gvTownships.FooterStyle.CssClass = "mGridtf"
gvTownships.AlternatingRowStyle.CssClass = "alt"
gvTownships.GridLines = GridLines.Both
'add columns
gvTownships.Columns.Add(tmpCategory)
gvTownships.DataSource = dstSuburbTowhShip
gvTownships.DataBind()
Code to add button to footer
Sub InstantiateIn(ByVal container As System.Web.UI.Control) _
Implements ITemplate.InstantiateIn
Case DataControlRowType.Footer
If columnName = "Calculation" Then
Dim btnCalculate As New Button
btnCalculate.Text = "Calculate"
btnCalculate.CssClass = "button"
'add handler
AddHandler btnCalculate.Click, AddressOf btnCalculate_Clicked
container.Controls.Add(btnCalculate)
End If
Case Else
' Insert code to handle unexpected values.
End Select
End Sub
Private Sub btnCalculate_Clicked(ByVal sender As Object, ByVal e As EventArgs)
Try
Dim btnCalculate As Button = CType(sender, Button)
Dim gvRow As GridViewRow = CType(btnCalculate.NamingContainer, GridViewRow)
btnCalculate.CommandArgument = "Calculate"
Catch ex As Exception
End Try
End Sub
End Class

i have a web form in which i ve a button which will open a sliding pop up box(jquery) on click of it. In the same page i ve also a linkbutton for downloading files. Now the problem is first time wen i click that button it does nothing. (will not open popup box). Once i click on download button and then if i click that button it will open popup box along with download dialog box. Why is it happening so... is it because am using same event click for both these.
but download option is implemented in gridview_rowcommand()..
