Custom Validator For MaxLength Property Of Textarea

May 16, 2010

I have quite a few text area's on my page and am wanting to limit the number of characters for each one. However each one should be able to have its own maxlength (i.e. one could be 20 characters and the other could be 100 characters). My validation on the page is all done using custom validation as the built in validation of .NET is not extensible enough for me to display my validation errors how I want to display them. So this is what im wanting to do:

Make a custom validatorPass a MaxLength value from the custom validator into the javascript function, this value must also be accessible from the code behindI can then run client side and server side validation on each textbox control. The problem I am having is passing a MaxLength value to client side script and to server side. Is there a property on custom validators which I can use to pass values around? For instance in Javascript I would want the value of the MaxLength and also the id of the Div which will show the characters remaining, and server side I would need to know the MaxLength. I have done lots of research on this and cannot seem to find an answer.

Set Width Of Textbox To Be Same As MaxLength?

Jun 10, 2010

Is there a way I can limit the width of a textbox to be equal to the MaxLength property? In my case right now, the textbox control is placed in a table cell as in this snippet:

<td class=TDSmallerBold style="width:90%">
<asp:textbox id="txtTitle" runat="server"
Text="Type a title here..be concise but descriptive. Include price."
ToolTip="Describe the item with a short pithy title (most important keywords first). Include the price. The title you provide here will be the primary text found by search engines that index Zipeee content."

(I know I should not use HTML tables to control layout..another subject for sure) but is there a way to constrain the actual width to the max number of characters allowed in the typed box?

DataSource Controls :: Binding An ObjectDataSource To A Property In Aspx Code, Not Code-behind

Dec 3, 2010

I want to bind an ObjectDataSource to a property in my asp page and I want to do it in the page's aspx code, not in code-behind. I've already done it in code-behind, as follows:


I'd prefer to get rid of the ugly code-behind and just do this in mark-up. Something like

This gives me a run-time error: Cannot create an object of type 'System.Object' from its string representation 'SelectedBook' for the 'DataSource' property.Is there a way of doing this declaratively and not in code-behind? Further, what if what I want is to actually use a child property of the property in question? For example, if my Book object has a ReaderComments collection, can I databind to it decaratively in the aspx mark-up?
