I have this datagridview in C#. When I load the form and the data is loaded (data is loaded from SQL Server Database) in this datagridview, one of my column is not visible also the width of columns is not correct, but when I search something and that data is loaded in the datagridview then everything is perfect. I don't want the scrollbar in the datagridview.
The following images shows the difference.
One column "Description" is not shown.
How I want the datagridview to show the data
You can use this code to change the width of the column in DatagridView:
DatagridView.Columns[your columns index].Width = your size;
You can turn off the auto-size mode with this:
DatagridView.AutoSize = false;
I have fixed the issue by setting Autosizemode to NotSet in Layout for DataGridView columns and giving them custom width values.
When I run the application and the data is loaded in the DataGridView I set AutosizeMode for one column to Fill and everything is perfect.
i have a question: is there any way to show a single row of a table in two rows? The problem is that my table has too many fields and is too wide. So, I think that maybe you can split each row in the table to make it in a row. For example (my idea in Excel, just for example):
Complete table
...and my idea
I hope for your help!
You can:
add a Tablix with 4 columns and without header
add a Rectangle in every detail cell
add 4 TextBox for every Rectangle: use 2 TextBox as labels and two TextBox as values
increase Rectangle height in order to put spaces between every rows
Once you perform this operation for value 1 and 5, you can copy and paste Rectangle in the other 3 cells and simply change label and value.
I have two columns in a table in ASP.NET page. In the first column I have a Grid View that gets populated from the database using the SQLDATASOURCE.
In the second column I have certain textboxes and checkboxes and buttons.
When I run the page in a browser, the data gets populated in the gridview which actually disturbs the alignment of the adjacent column that contains the textboxes and the checkboxes.
These textboxes and checkboxes that are supposed to be visible at the top of the column are now visible at the center because the gridview data populated disturbs it.
Please help with this as I want these textboxes and checkboxes in the second column to be visible at the top of the column.
You need to set the vertical alignment of your second table cell:
<td style="vertical-align:top">xx</td>
The default value is "middle" which is why your content gets pushed to the middle as the vertical height of the table cell gets taller than your content.
I am binding a DataTable to GridView. It does not adjust to height and width of the DataTable. How can I the strech the width of the grid that i shows all the columns and height shrink if the rows are few.
just go to the properties of your datagrid =>
and then at the section Layout=>
AutoSizeColumnsMode set it to Fill...
To autosize the columns to fit the data (width-wise) and then autosize the form to fit the gridview (width-wise), use the following code:
foreach (DataGridViewColumn column in dataGridView1.Columns)
column.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
this.Width = dataGridView1.Width + 100;
where dataGridView1 is the name of the Datagridview in this example, and this is refering to the instance of the form. The 100 is a constant for how many pixels wider you want the form than the datagridview. (note: you may want some width checking to make sure you form and data gridview aren't wider than the user's screen)
To autosize the datagridview to fit the rows (height-wise) and then autosize the form to fit the gridview (height-wise), use the following code:
int totalRowHeight = dataGridView1.ColumnHeadersHeight;
foreach (DataGridViewRow row in dataGridView1.Rows)
totalRowHeight += row.Height;
dataGridView1.Height = totalRowHeight;
this.Height = dataGridView1.Height + 100;
where dataGridView1 is the name of the Datagridview in this example, and this is refering to the instance of the form. The 100 is a constant for how many pixels higher you want the form than the datagridview. (note: you may want some height checking to make sure you form and data gridview aren't taller than the user's screen)
First, your form would have to be big enough for the DataGridView to expand and show all of the columns. In the screenshot, it doesn't look wide enough. You can set the size of the datagridview manually, but it is rare that you know the exact width of each column at design time because you don't know how much will be in each column at run time. For example, your Invoicedescription column could have strings that vary in length.
What I typically do in cases like yours is to put a splitter control on the form. The text box at the top and the Import Invoices button would go in the top panel of the splitter control, and the DataGridView would go in the bottom panel. Then, set the Dock property of the DataGridView to fill the bottom panel of the splitter control. This way, when the user resizes the form the DataGridView will grow/shrink with it.
You can further control the way the columns appear by setting the DataGridView.AutoResizeRows property.
Just giving this as an option, I'm not aware of any way to have the grid automatically resize to the data it is displaying. You may be able to calculate the height/width of the rows and then manually resize the grid in code, but I would make sure I really needed that requirement first.
This works assuming that all the rows have the same height, even when the first header row has different height (for example long headers are wrapped)
If List.RowCount = 0 Then
List.Height = 0
ElseIf List.RowCount = 1 Then
List.Height = List.ColumnHeadersHeight
Else
List.Height = List.ColumnHeadersHeight + List.Rows(1).Height * (List.RowCount + 1)
End If
Set the datagridviewautosizecolumn to "All"
Then, in the form that contains the datagridview, assuming you populate the data grid view in the load event handler or some other event handler as desired wherever the data is loaded (must be after data is loaded) type: (VB)
Me.Width = DataGridView1.Width + 50 ' Number of pixels wider than the datagridview you want the form to be.
datagridview1 is the name of your datagridview control.
Me refers to the form that contains the datagridview control.
You may need to either maximize the window or anchor it to the top and left to ensure fitment depending on how large of a dataset is being populated.
I know this is probably already answered but just in case I post here what helped me to autosize the whole datagrid view by AllCells:
After your Datasource load, paste the following
dataGridView1.AutoResizeColumns();
dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;
i used this in IronPyhton to fit the table
1: LayoutPanel.AutoSize = True
2: dataGridView.AutoSize = True
3: self.AutoSize = True
I used a datagridview in my winform application.
I load datagrid with a dataset that have 4 columns.
Next I want to add a column between column2 & column3.
How to I do this.
Thanks.
You can use Insert method on DataGridView.Columns collection. For example,
var column = new DataGridViewTextBoxColumn();
// initialize column properties
...
myGridView.Columns.Insert(2, column);
Preferably, this should happen after the data binding.
Using the Visual Studio Designer, you can simply add columns of every kind in the options of the DGV.
You can even set the position of the columns by drag&drop.
If you can't or don't want to use the Designer VinayC told you to do it the code-way.
