"is not working" is not a helpful error message.
Does it compile? Run? Is there an error message of some form? What does it do that you didn't expect, or not do that you did? Does the textbox value parse ok?

code is not giving any error in compilation but when i give value <25 in the text box its not disabling that part of the page.

Solution 1

Try something like this

C#

if ((isParsed) && (value <= 25) && (ddlContractorTypeID.SelectedValue != "C"))

this also not work.

Code looks okay...Try and debug things by adding a break point and check values of each variables. it may help you ? or check the ddlContractorTypeID.SelectedValue in the quick watch.

see if isParsed=true

Check the comments inside the code block.

C#

protected void txtContractorBusinesscapacity_TextChanged(object sender, EventArgs e)
    {
        if (!string.IsNullOrEmpty(txtContractorBusinesscapacity.Text))
        {
            int value = 0;

            bool isParsed = int.TryParse(txtContractorBusinesscapacity.Text, out value);

            // Put a break point here. Check what are the values of isParsed, value and ddlContractorTypeID.SelectedValue by hovering mouse on them. Are they satisfying the "if" condition?
            if (isParsed && value <= 25 && ddlContractorTypeID.SelectedValue != "C")
            {
                DisableConsumerPart();
            }
            else
            {
                EnableConsumerPart();
            }
        }
    }
