Is it possible to have an imagebutton in datagrid. When clicked will produce a larger version in detailsview
|

Give some more details of the problem. Whta i have understood is on click of a imagebutton(which is inside the datagrid) you want to display some more details of that record. If it is so then you can easily do that. What you need to do is to place the image button in the itemtemplate of the datagrid and handle the click event which you can do with onItemCommand event of the datagrid.

I have a database with name, image, etc and as far as i know you cannot click on an image in a datagrid so i want to us the datagrid to show like thumbnails of the images, and when clicked, retrieve the the image and other data from the database and display it in detailsview using master/detail.
|

You can display the image in the datagrid and also can handle the click event of that image. But do you have your image saved in the database or only the image name which you are retreiving from the database and displaying the image from a certain location?

To be honest, when i filled the database i can't remember whether the image is stored in the database or just the location address. What would be the difference?
Thanks for talking to me!!!!

There is too much difference, actually in normal case only the image name is being stored in the database and the image is being saved at some place at the server, so while retreiving only you have to get the name and attach it with the path of the image(where the image is stored) and display it. In the other case the complete image is being save into the database which is rather a bit complicated. You need to have separate datatype in the database to store the image. For details of how to save image to the database you can check this link:

Hello All,
I am creating a custom control which has a capability to create controls as requested. It means, if I ask custom control to create one textbox and two dropdowns, at runtime it will create those and show.
Now I would like to have cascading dropdowns in custom control. Do anyone have an idea how to add a cascading dropdown [ATALAS TOOLKIT CONTROL] from code at runtime?
Any help appreciated.
Thanks in advance.

I have a problem with CustomValidator. I want to validate 2 controls. IsValid=false when DropDownlist selected item (some value) and some textbox.text ="". I don't know how to write clientValidation script ( no javascript, no vbscript language experience ). Please help

just add the custom validator to your page and set its ClientValidationFunction function to the name of a javascript function that will do the validation. You don't have to set its 'controltovalidate' property as you will be interogating 2 controls.
Put a section in the header of your page that defines the function you just referenced. In this function, use the DHTML DOM to grab the elements you are interested in and interogate them.
your javascript function would look something like:
function CustomClientValidate(source, arguments)
{
ddl_Items = document.getElementById('ddl_Items'); //note the string in getElem.. must match the clientid of your asp.net dropdown.
or
txt_myentryfield = document.getElementById('txt_myentryfield');
and then something like
arguments.IsValid=true
var itemSelected = false;
for (n = 0; !itemSelected && n < ddl_Items.items.count; n++)
if (ddl_Items.items[n].selected)
itemSelected = true;
if (txt_myentryfield.value == '' && !itemSelected)
arguments.IsValid=false;
}
I did not try to run any of this and I may not be remembering how to iterate the items in the drop down on the client (a select on the client), but you can look that up elsewhere. This is the generate idea.

on page load i have to bind a datalist control in another datalist control.
|
|
|
|
|
In the page load you bind the first datalist and in the itemdatabound event of the parent datalist you bind the child datalist.

Hi Apurva,
thanks a lot ! The help worked out..!
To give the detail of the problem i have two tables ,Master and the Detail table.
I have to bind the Detail table in the inner datalist control.
Could you please guide me how to create relation with in the datalist controls?
|
|
|
|
|
Actually what you need to do is put the child datalist in the itemtemplate of the parent datalist and then as i told first bind the parent datalist and then on itemdatabound event of the parent datalist you first find the child datalist and then bind it. onitemdatabounf event fires for each and every record of the datalist and there you can get the associated child records for the parent ID. you can use filter for that.

Hi,
By using regular expression you can able to do it.
Just go through the below coading:
<asp:regularexpressionvalidator id="regexpName" runat="server"
="" errormessage="This expression does not validate." controltovalidate="txtName" validationexpression="^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$">
