Maxpagestatefieldlength in config

Question

I have just got a quick question. When we give the config settings as

maxPageStateFieldLength = "2048"

then the value 2048, is that the number of characters or if it is the size of the hidden field then what is the unit of it like bytes etc?

Also, how do we know what value can we give for our project?

Can anyone please help me to find out the answers for these questions

What I have tried:

<pages enableEventValidation="false" controlRenderingCompatibilityVersion="4.0" maxPageStateFieldLength="2048">

Solution 1

Always refer to the documentation page:
Page.MaxPageStateFieldLength Property[^]

is that the number of characters or if it is the size of the hidden field then what is the unit of it like bytes etc?

This is the maximum length, in bytes, of the page's state field.

how do we know what value can we give for our project?

Having an idea of the average size for the state field in your project is a start. Or, you can set it to -1 as suggested in the documentation, and forget about it (unless this setting cause some sort of actual issue).

I actually have an issue with my ViewState, where it is intermittently throwing an error occurred in a few pages in my project and so I am trying to add the maxPageStateFieldLength in the config settings. But I am not sure what value should I have to give. I tried with 40/60 but still got the issue. Now I have given the value as 2048 and no errors till now. I am not sure whether I have given very high value than needed for my project.

2048 bytes (2 Kb) does not seem so huge nowadays. If it solved your issue, without causing timeouts or other unpredicted results, then I would say it fits.
If you still wonder whether or not it is appropriate, then log view states' sizes somewhere in your server code, and try to optimize the value with acquired knowledge.

Thank you so much for your help. I just found that the view state for my page is 59928 and so even 2048 also didn't work. Now set the value to 59930. Fingers crossed
