Setting AutoSizeMode in the designer

560

Stefan posted over 15 years ago

I have a UltraGrid that is bound at runtime. I design my bands and columns in the design mode and set the AutoSizeMode-property of my columns to AllRowsInBand. At runtime, I use the setdatabinding()-method to bind my data to the grid, but this seems to throw away some of my settings I set in the designer. The width of the columns seems to be the default-width shown in the designer, there is no effect of the AutoSizeMode. When I use PerformAutoResize after the databinding, this works just like expected. Is there a way to re-set the designer settings after the databinding? I would like to resize all my columns to the maximum width of the cells, except the last column. The last one should use the remaining space in the grid or more, when the column would not fit into it.. Thanks in advance, Stefan

Hi Stefan,
If the grid is losing it's layout when you call SetDataBinding, it means that the data source you are binding to does not match the schema you set up at design-time in some way.
Perhaps one of the band or column keys does not match up.
Personally, I find it much easier to set up the layout of my grid using the InitializeLayout event, rather than the designer. The VS form designer tends to be a bit flaky when dealing with data source notifications and can sometimes cause the layout to be reset when it doesn't seem to need to.

Hi Mark, thanks for your answer. I set up one single band with one column to check if AutoSize will work with this easy example. At runtime I created a DataTable with the name of the band. The dataColumn has the same name that is defined as key for the column in my grid. I set the column to AutoSize with each VisibleRow, but the width is still the "default-width". Do you have an idea what could be the problem that the AutoSize-property is still ignored? Thanks, Stefan

Maybe I am confused. What AutoSize property are we talking about here? And what does it have to do with the VisibleRow?
The only AutoSize property I am aware of is the one on Control, which the grid inherits. But this was added to control in CLR2 and the grid does not support it. Even if it did, it would not affect the columns or rows in the grid, as AutoSize is intended to size the control itself within it's container.
So what exactly are you trying to auto size? You might be looking for AutoFitStyle. Or perhaps the PerformAutoResize method on the columns.
