I am trying to compute the height of the row I'm inserting into my excel sheet. The row's cells are formatted with WrapText=true, so the height of the row is not fixed.
Accessing row.Height will return null.
I was thinking of using something similar to Graphics.MeasureString where I also specify the width constraint in order to retrieve the height.
Didn't find any relevant info online. Any help would be appreciated.
See my post here using Graphics.MeasureString. It works very well.

so i'm bounding my DataGrid with some data from an sql query, when I show it everything looks fine, all the data/columns/rows are there.
Now what I want to do is set fixed width to certain columns ( Name, Email, Address) and if the text excedes that width, i want it to be hidden. I've seen a lot of ways to change the width in tables, but this doesn't work with DGV.
I also tried DataGridView1.Columns[1].Width() but DGV.Columns doesn't have a width option.
I'm not adding any code because its a general questions, if you have any examples, that would be great. Thanks
Columns does not have width property but Cells have it. you can set it at cell level.
TestGridView.Rows[0].Cells[0].Width
Use TestGridView.Rows[0].Cells[0].Text property to get value of the cell and you write logic to check if it exceeds the specified width.
I create C# programmatically excel file with merged cell. User OpenXml library. I need AutoFit merge cells as single cell. But I can't change merged cells hight. Is it possible to programmatically change?
You can't change the cell height as far as i know. But, a nice workaround would be to change the row heigth instead of the cell heigth.
Remember that in vb you can do something like this: Rows(3).RowHeight = 25;.For the C# way you should take a look at this: MSDN Reference. Hope it helps!
I was wondering if anyone has come up with a workaround to this problem. I've noticed that the AutoFitColumns() method is failing on columns with merged cells. I've included a basic code example below:
var cellRange = worksheet.Cells[1, column, 2, column];
cells.Merge = true;
cells.Style.HorizontalAlignment = OfficeOpenXml.Style.ExcelHorizontalAlignment.Center;
cells.Value = "Some Text Goes Here";
worksheet.Cells.AutoFitColumns();
The resulting worksheet will have the cells in rows 1 and 2 merged (correctly) for the column in the column variable, but that particular cell is disregarded by the AutoFitColumns() method.
Any help would be appreciated.
Basically...
AutoFitColumns is documented to ignore merged cells. It isn't failing, at least in the sense of being defective.
AutoFit within Excel ignores merged cells, too.
Apparently up through Excel 2007, you cannot use the AutoFit feature for rows or columns that contain merged cells at all.
I've only tested with Excel 2013, which seems to behave differently:
Auto-fitting a row ignores all row-merged cells in that row.
Auto-fitting a column ignores all column-merged cells in that column.
In other words, you can use AutoFit in rows and columns with merged cells, it'll just ignore any cells that have been merged along the same dimension you're auto-fitting.
Desired effect of AutoFit w/r/t merged cells? (+ workarounds)
Finally, I'm not sure whether I see how it makes sense to auto-fit with respect to a merged cell. For example, suppose you have a merged cell at A1:B1 with content that fills a default two-column width.
If you auto-fit on column A, what is supposed to happen? Is column A supposed to become wide enough to fit all of A1:B1, sort of like treating the merged cell as if it's content existed only in A1, the top-left original cell? That might be reasonable, insofar as I can't immediately see whether strange behaviors might be implied in some circumstances.
If something like that is desired, I'd insert the content, auto-fit, and only then merge.
But what if you want to auto-fit on column B, in a situation like this:
Here, you might want column B to get wide enough so that all of the content in A1:B1 shows. (The content is just the text "well hello world".)
There's no one-liner for this, I'm afraid. Here's one way to do it, though:
Insert the content in the as-yet-unmerged top-left cell.
Save the current width of this cell's column.
Auto-fit the column.
Save the new column width.
Reset the column width to what you saved in step 2.
Merge the cells you want to merge.
Total up the widths of all your merged columns but the last one.
Subtract this total from the width you saved in step 4.
Set the last merged column's width to the result of step 8.
More generally, you can split up the total auto-fitted width from step 4 among the merged columns in any way you see fit.
To do all this, you'll want to use ExcelColumn.AutoFit and ExcelColumn.Width (and ExcelWorksheet.Column to grab the ExcelColumn objects).
But most simply...
If your content is static (or at least dynamic but not too variable in length), you can simply set reasonable fixed width(s) for the column(s) in question, distributed however you'd like.
I have read so many article to do my task. I want to use wrapmode to increase the height of the cell when the content reaches the cell width. The text want to display in a new line in that cell only.
So many articles refer me to set
dataGridView1.DefaultCellStyle.WrapMode =DataGridViewTriState.True;
dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells
I have set these two properties to may datagridview.. Still the text is not wrapping in the cell. Am I missing anything??
On my windows form, I need to programatically set the width of columns in the grid view. I am using the following code:
this.dgridv.Columns[columnName].Width = columnWidth;
The above stmt runs without any error. But, the column width remains unchanged. If I insert a breakpoint and check the value of width after the stmt runs, it is still 100, which I guess is the default value of datagrid column width.
Is there something else I need to do apart from this? Are there any values I need to set before changing the column width?
Any help or pointers on this are highly appreciated.
Thanks :)
Have you got the AutoSizeColumnsMode set to Fill?
If you have you'll need to set the FillWeight property instead. This isn't a simple width but the proportion of width / no. columns that this column takes up.
If you haven't resized the columns it will be 100.0.
If the column has been widened it will be > 100.0.
If the column has been shrunk it will be < 100.0.
Widening one column, by definition, shrinks the rest.
This worked:
this.dgridv.Columns[columnName].AutoSizeMode= DataGridViewAutoSizeColumnMode.None;
this.dgridv.Columns[columnName].Width = columnWidth;
To reset it back, I am using:
dgvCol.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
dataGridView1.Columns[index].Width = 150;
This line of code will set the column width programatically.
