Two grids in one form

Posted on by hfou

Hello,

I would like to create a new form. I have two tables, table A and table B. Between table A and table B there is some relation, R. On the form, there have to be two grids, one next to each other. In the first grid, there will be values of table A. When the user selects the value in the first grid (from table A), in the second grid will be shown a values from table B, based on relation R.

I am not sure if there is some pattern, that could be used for this? If there is not any pattern, where these grids would be next to each other, is there some pattern, where the grids would be below each other? I have tried to create my own "custom" patter for the "below" case, but I am not sure, how to add the values, when I add the datasource to the form, then in a pattern, I add some grid and in the grid, I add e.g. string, select data source on that string and the field, but when I open the form, the grid is empty. Am I missing something, please?

Many thanks.

Hi hfou If I understand this question correctly you want to show records like below screen shot ?

If Yes, Then this can be done using Task Double pattern.
Please refer below screen shot for design help.

Change link type to active-

Build your form and check the result, Please mark this as correct answer if it worked.

When choosing a form pattern and figuring out how to implement something, it's useful to look at existing forms in the standard application. For example, look at purchase orders - there is a grid for headers and another grid for lines. Or maybe you want a simpler form, e.g. simple list with details, when there is another grid in details. If you look into documentation (Simple List and Details form pattern), you'll find an example there: ExchangeRate form.

Vijay is right that you should have each grid associated with one data source, and the data sources should be linked, but the link type should normally be Delayed, not Active.

Hi Vijay,

thanks, yes, I was looking on this pattern, but in the documentation, there is the information, that this pattern should not be used for the form created by scratch, don't know why. There is other problem, that this pattern shows the grids below each other, not next to each other

Hi Martin,

yes, the exchangerate form would be ideal. I just do not know what I am doing wrong, I create a form, add data source, but can not see any values in it. I have created the form based on the pattern, added data source, set the data source in properties, added field, in the properties of the field, I have selected the data source and then selected the field. But nothing is shown...

Are you talking about the first grid?

First of all, make sure that the table contains some data in the current company. Maybe the result is correct, because there is nothing to show.

Use just a single data source for the moment. Make sure that the grid refers to it in its Data Source property. Then drag fields from the data source to the grid. Build the form and try it once more. If you don't see anything, verify again that you're in the right company. If you're running the form from Visual Studio, you can set the company in project properties.
