I have some Code in VB that is looping through a gridview's rows and is checking the values of a certain collumn, I have written some code inside the if statement that creates a clickable label inside the cell for when the cell is "", I have already written a bit of code that could create my label but I'm not too sure how it would create it inside row.Cells(8)
I was wondering if could get some assistance with how I should be doing this?...
Here's my Code:
For i As Integer = 0 To GridView1.Rows.Count - 1
Dim row = GridView1.Rows(i)
Dim rowHeaderCell = row.Cells(8)
If rowHeaderCell.Text = " " Then
Dim lbl As New Label
lbl.Size = New System.Drawing.Size(159, 23)
lbl.Location =
lbl.Text = "label text goes here"
Me.Controls.Add(lbl)
End If
Next
Thankyou in advance!
To make a clickable label change the type of the column to : [DataGridViewLinkColumn]
here is the code to replace the Empty cell value by the value of LBL:
For i As Integer = 0 To GridView1.Rows.Count - 1
If GridView1.Rows(i).Cells(8).Value.Trim = "" Then
Dim lbl As String
lbl = "label text goes here "
GridView1.Rows(i).Cells(8).Value = lbl
End If
Next

I am dynamically creating checkboxes in VB.Net and an .aspx page, based on values in my db. I'm placing them in a two column table for ease of alignment. this part works fine.
Private Async Function InitForEditAsync() As Task
Dim docList = Await GetLoanApplicationConfigurationDocs()
Dim row = New HtmlTableRow()
Dim cell = New HtmlTableCell()
Dim i = 0
For Each doc In docList
Dim chkBox = New HtmlInputCheckBox()
Dim lbl = New Label()
Dim remainder = i Mod 2
chkBox.ID = "chkDocId" + doc.Id.ToString
lbl.Text = doc.DisplayName
cell.Controls.Add(chkBox)
cell.Controls.Add(lbl)
row.Cells.Add(cell)
cell = New HtmlTableCell()
If remainder <> 0 OrElse i = docList.Count() - 1 Then
tblEdit.Rows.Add(row)
row = New HtmlTableRow()
End If
i += 1
Next
End Function
Now I need to retrieve the values without knowing the id's but am not having any luck. I tried this:
For Each chkBox As HtmlInputCheckBox In pnlEdit.Controls.OfType(Of HtmlInputCheckBox)
but the checkboxes are not returned in the list of controls. The table is, but there are no rows in the table object when I explored it in the control collection and when I tried this:
For Each row As HtmlTableRow In tblEdit.Rows.OfType(Of HtmlTableRow)
If it will help, here is a Snip of the UI and the HTML that is created:
Any suggestions are appreciated. Thanks in advance.
Based on some ideas I got from another site, I'm going to rewrite this using the asp:CheckBoxList. apparently it binds like a datagrid and you can enumerate through it. Seems like what i need.
UPDATE: Everything I posted to start was resolved with five lines of code! "cblDocList is my asp CheckboxList and docList is my ienumerable of objects.
cblDocList.RepeatColumns = 2
cblDocList.DataSource = docList
cblDocList.DataTextField = "DisplayName"
cblDocList.DataValueField = "Id"
cblDocList.DataBind()
It’s something you can do through a loop for each row and each cell or using Linq to have only cells that have controls of type HtmlInputCheckBox inside.
I have simplified your code to be able run that here also shows you an example to achieve your task. Obviously you must change following your exigences .
Hope I well understood :)
Dim tblEdit As New HtmlTable
For k As Integer = 0 To 10
Dim cell = New HtmlTableCell()
Dim row = New HtmlTableRow()
Dim chkBox = New HtmlInputCheckBox()
Dim lbl = New Label()
Dim remainder = k Mod 2
chkBox.ID = "chkDocId_" + k.ToString
chkBox.Checked = remainder = 0
lbl.Text = "Text indicator of CheckBox nr:" + k.ToString
cell.Controls.Add(chkBox)
cell.Controls.Add(lbl)
row.Cells.Add(cell)
cell = New HtmlTableCell()
tblEdit.Rows.Add(row)
Next
Dim checkBoxes As IEnumerable(Of HtmlInputCheckBox) =
(From mRow In tblEdit.Rows).Select(Function(mr)
Dim cb = (From cc In CType(mr, HtmlTableRow).Cells
Where CType(cc, HtmlTableCell).Controls.OfType(Of HtmlInputCheckBox).Count > 0
Select CType(cc, HtmlTableCell).Controls.OfType(Of HtmlInputCheckBox)()(0)).FirstOrDefault
Return CType(cb, HtmlInputCheckBox)
End Function).ToList
For Each checkBox In checkBoxes
Debug.WriteLine("CheckBox ID: {0} Checked: {1} ", checkBox.ID, checkBox.Checked)

Hi I am trying to add two controls into a table cell the code is below. Unfortunately the hyperlink is always outside the table cell, whilst the label is inside. Individually they are working fine but together not so good, could somebody help me please.
Dim iCell As New TableCell
Dim lbl As New Label
lbl.Height = Unit.Pixel(100)
lbl.Width = Unit.Pixel(150)
lbl.Style.Add("padding", "5px")
lbl.Style.Add("border-radius", "10px")
lbl.BorderStyle = BorderStyle.Solid
lbl.BorderWidth = Unit.Pixel(1)
lbl.BorderColor = Color.Black
lbl.Font.Size = 9
lbl.Text = "Event: " & dt.Rows(y).Item("eventname")
lbl.BackColor = ColorTranslator.FromHtml(dt.Rows(y).Item("roomcolor"))
Dim hyp As New HyperLink
hyp.Font.Size = 9
hyp.Text = "Modify"
hyp.NavigateUrl = "modify.aspx"
iCell.Controls.Add(lbl)
iCell.Controls.Add(hyp)
iCell.VerticalAlign = VerticalAlign.Top
tRow.Cells.Add(iCell)
I dynamically create textboxes by a click of a button... then i would like to get the values from the textboxes that i created to insert to the database.. I use VB.NET 2008.
this are some sample codes..
For x As Integer = 0 To mydt.Rows.Count - 1
l = New Label()
tb = New TextBox()
tb.ID = x.ToString()
l.ID = x.ToString
l.Text = bb
Panel1.Controls.Add(l)
Panel1.Controls.Add(tb)
tb.Text = mydt.Rows(x).Item(0)
Next
I just assumed that you are working in winforms, You can do it by assigning unique name to your text boxes like this,
For x As Integer = 0 To mydt.Rows.Count - 1
l = New Label()
tb = New TextBox()
tb.name = "txt" & x 'Name your text box
tb.ID = x.ToString()
l.ID = x.ToString
l.Text = bb
Panel1.Controls.Add(l)
Panel1.Controls.Add(tb)
tb.Text = mydt.Rows(x).Item(0)
Next
So in the next step, since you are adding those textboxes in to panel1, you can fetch it directly from that container like below,
For x As Integer = 0 To mydt.Rows.Count - 1
MsgBox(Ctype( panel1.Controls("txt" & x),textbox).text)

I'm using NPOI to output excel from Asp.Net. I want to set bold and normal style to my cell but it is working for few cell and not for remaining cell.Please have look on following example:
Dim hssfworkbook As New HSSFWorkbook()
Dim sheetOne As HSSFSheet = hssfworkbook.CreateSheet("Sheet1")
hssfworkbook.CreateSheet("Sheet2")
hssfworkbook.CreateSheet("Sheet3")
Dim cellStyle As HSSFCellStyle = hssfworkbook.CreateCellStyle
cellStyle.Alignment = HSSFCellStyle.ALIGN_CENTER
Dim font As HSSFFont = _hssfworkbook.CreateFont()
font.Boldweight = HSSFFont.BOLDWEIGHT_BOLD
cellStyle.SetFont(font)
For i = 0 To 9 Step 1
'I want to add cell style to these cells
If i Mod 2 = 0 Then
Sheet1.CreateRow(i).CreateCell(1).SetCellValue(i)
font.Boldweight = HSSFFont.BOLDWEIGHT_BOLD
cellStyle.SetFont(font)
Sheet1.GetRow(i).GetCell(1).CellStyle = cellStyle
Else
Sheet1.CreateRow(i).CreateCell(1).SetCellValue(i)
font.Boldweight = HSSFFont.BOLDWEIGHT_NORMAL
cellStyle.SetFont(font)
Sheet1.GetRow(i).GetCell(1).CellStyle = cellStyle
End If
Next
Actually code is working fine but i don't know the particular situation from where and why its stops working for remaining few rows. Its not working properly for all cells and from that particular cell the bold and normal property stops working on whole sheet like sheet2 and sheet3.
You have to use multiple styles because a change to a style affects everywhere that style is referenced in the sheet.
Dim hssfworkbook As New HSSFWorkbook()
Dim sheetOne As HSSFSheet = hssfworkbook.CreateSheet("Sheet1")
hssfworkbook.CreateSheet("Sheet2")
hssfworkbook.CreateSheet("Sheet3")
Dim BoldFont As HSSFFont = hssfworkbook.CreateFont()
BoldFont.Boldweight = HSSFFont.BOLDWEIGHT_BOLD
Dim NormalFont As HSSFFont = hssfworkbook.CreateFont()
NormalFont.Boldweight = HSSFFont.BOLDWEIGHT_NORMAL
Dim cellStyleBold As HSSFCellStyle = hssfworkbook.CreateCellStyle()
With cellStyleBold
.setFont(BoldFont)
.Alignment = HSSFCellStyle.ALIGN_CENTER
End With
Dim cellStyleNormal As HSSFCellStyle = hssfworkbook.CreateCellStyle()
With cellStyleNormal
.setFont(NormalFont)
.Alignment = HSSFCellStyle.ALIGN_CENTER
End With
For i - 0 To 9 Step 1
If i Mod 2 = 0 Then
With Sheet1.CreateRow(i).CreateCell(1)
.SetCellValue(i)
.cellStyle = cellStyleBold
End With
Else
With Sheet1.CreateRow(i).CreateCell(1)
.SetCellValue(i)
.cellStyle = cellStyleNormal
End With
End If
Next
I have the following code:
Dim i As Integer
For i = 1 To 20
Dim captionTextBox As TextBox = DirectCast(Me.FindControl("news_Image" + i.ToString() + "CaptionTextBox"), TextBox)
Dim deleteCheckBox As CheckBox = DirectCast(Me.FindControl("Image" + i.ToString() + "DeleteCheckBox"), CheckBox)
If Not deleteCheckBox.Checked = False Then
If Not captionTextBox.Text = "" Then
'Insert the value of the textbox into the column like news_Image1Caption, news_image2Caption nased on the value of i
End If
End If
Next
Where the comment is in the code above, I need to insert the value of the textbox (text) into Linq columns. For example: articleToUpdate.news_Image1Caption, news_Image2Caption, but I need to change the number after news_ to the value of i in the for loop. How can I do this?
Thanks
Luke
Did you try to set the ID column to Auto-Generated Value = true ?
INSERT INTO [dbo].[s_Tbl]([ID], [news_Image1Caption], [news_image2Caption]) VALUES (...)
