Height Value of Rect Transform cannot be changed via script

Questions & Answers

I have a scroll view and contains child objects arranged in the form of grid layout, using grid layout group. This is the sample image of my grid layout.

The pic images and the texts are generated at run time using prefabs and script. The image and text are included in a single game object and converted into a prefab. The list is populated at run time from a server. The parent game object of these prefabs has a grid layout group and content size fitter is added to it.

Now coming to the problem, since there is content size fitter, the text in the last 3 images is cutoff and cant be viewed properly. I need to increase the height of the content rect transform a little bit more so that the bottom most text is also view able properly. But the height can’t be edited due to content size fitter. I tried to obtain the height using the code:

float height = imageContainer.gameObject.GetComponent().rect.height;

but it was returning 0 only. The vertical fit of min size is disabling the height value. Can someone please help me in this issue.

You should try to use something like this :

imageContainer.gameObject.GetComponent<RectTransform>().offsetMin = new Vector2(rectTransform.offsetMin.x, newBottomValue);
imageContainer.gameObject.GetComponent<RectTransform>().offsetMax = new Vector2(rectTransform.offsetMax.x, newTopValue);

Where offsetMin.x is left, offsetMin.y is bottom, offsetMax.x is right and offsetMax.y is top.
