Setting ImagesFolderPath at runtime

[Doug]

So I am trying to set the ImagesFolderPath at runtime, but am having problems please help.

Let me setup the scenario first.... I have a webpage that has several different controls.  One control is a dropdown list that contains numeric codes.  When a code is selected it populates the rest of the page.  I want to set the ImagesFolderPath, once this numeric code is selected.  I have tried putting code in the Load and Databinding events the ImageGallery never reloads.  The control just sits on the page and does not appear to ever reload or rebind with the new ImagesFolderPath.


Please help

Hello Doug,

Thank you for contacting us.

I have created a sample RadGrid web site to demonstrate how you can achieve the requested functionality. Please run the attached application and let me know if it helps you.

I have a similar problem when trying to change the ImagesFolderPath from code. So does this mean that this property is design time only? It would be helpful if the documentation said so.

The sample application you provided does work but it adds quite a bit of complexity to the page code just to change a single property. It is not immediately apparent how to change that property in the sample other than by use of the combobox in the example. That is impractical for my project. I just want to pass a variable to the gallery.

Do you have a sample that shows how this can be done?

Hi Brian,

With the next release you will simply be able to use the following approach in order to achieve this requirement:

protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
{
    RadImageGallery1.ImagesFolderPath = "DifferentPath";
    RadImageGallery1.CurrentItemIndex = 0;
    RadImageGallery1.Rebind();
}

Until then, I'm afraid there is no alternative solution than the approach demonstrated in the mentioned sample.

Please free to let us know if new questions arise.

      RadImageGallery1.ImagesFolderPath = "images";
            RadImageGallery1.DataBind();

Hi Angel,

I'm not sure what you had in mind, but the Rebind() method should work pretty good, too.
You can also check the following code-library for customizing the RadImageGallery control:
