I want to acces Container Dataitem in <%.
Is it possible to do that?
I want to pass the current dataitem to a method and check if it's valid then show a button.
This <% %> is located inside a repeater.
<%
if (Validate( (Order)Container.DataItem))
{ %>
<asp:button text=edit>
<% }%>
input type=..... value="<%= ISO3166CountryList.GetCountryByCode("IE", CurrentLocale).Name %>" />
I'm looking to replace the hardcoded IE with something like
<%#(Container.DataItem as PhoneNumber).ISO%>
No variations of what I've tried worked. How can I get a databinded value when within a <%= code block? Do I need to use an intermediary variable?
I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.
I am collecting user roles into a single dimension string array.
I have a repeater that its source set to that array. The repeater template includes list of checkboxes for the values in the array.The checkbox text is set to: Text='<%# Container.DataItem %>'
All is good till this point.
But I am trying to call a javascript function triggered by clickign a checkbox and pass it the container.dataitem, but the javascript doesn't seem to be reading the value and either complain about string not being in correct format or that treats the container.dataitem as a liter. This is the trial that didn't work (I tried many different things too):
DetermineVal(<%# DataBinder.Eval(Container.DataItem) %>);
determineval is my javascript function
Can I do that with a single dimension array?
I have a ListView in which i have a function that creates images for users. I pass userGender,userImage1name,userIsImage1Aprooved values to the function in which i generate image.ie. if user has approved image i return it back, otherwise i return default image based on gender.y question is, is there any way to avoid passing 3 parameters to that function and to pass whole DataRow so i can get values of columns i need?In reality i pass about 12 parameters just made it easy for you.ie. i want to achieve something like that <%# GetImage(Container.Item) %> while in GetImage() i would be able to access Item("some_column_name") or C# version Item["some_column_name"].

View 5 RepliesIn a nested GridView (GridView inside a template column of parent GridView). I am binding child GridView to a DataTable in parent GridView's RowDataBound event. this works as it should. But the problem i am facing is in Child GridView's RowDataBound Event, when i try to access e.Row.DataItem property it returns null. I am expecting it to return DataRowView Type. which i will then use to set values of TextBox's.

What is the proper way to check for null or empty strings on dynamic objects? This is the only solution I've found so far:
if (admin.PasswordHash.GetType() == typeof(DBNull) || admin.PasswordHash == string.Empty)
If the field is null, the object returned is DBNull.Value, but if the field is empty string, it's return as a System.String object. This makes it impossible to do regular "admin.PasswordHash == DBNull.Value" check, as that will fail whenever the field has been set to empty string. Is my example the right (and only) way to go?
I'm trying to pass a string value to a javascript function from a LinkButton's OnClientClick event, but the function is receiving "<%# Container.DataItem %>" instead of the value. Here's the code:
OnClientClick="javascript:SaveQuotaGroupCode('<%# Container.DataItem %>');"
The container is a collection of strings. Why is it not evaluating?EDIT: This is located in a nested ListView. The datasource for the inner ListView is a property in the datasource of the outer ListView.
I am trying to access the current 'active' top level node from a sitemap repeater from outside of the ASP.NET repeater used to render it, this is for CSS styling purposes as I want to place the child nodes on the subsequent row with different styling horizontally. At present I have the following code which I can't get to display correctly using CSS.
[code]....
I would like to display the child nodes on the next light blue element which I can do perfectly well from a seperate div if this was not rendered using a child repeater. In the image below Blog and Services are top level nodes and their subseqent nodes (2 for each) should be displayed on the light-blue row below. Is this possible?
I use a ItemDataBound for a repeater.But i use 2 kinds of linq querys to bind it.Some of them has a MerkID, and some doesnt have this item.So its easy i need to do this:
if(e.Item.DataItem.Contains("MerkID"))
{
//Code for linq query 1
} [code]...
So of course the if selection doesnt work, but how can i do that? I already tryed this:
DataRowView drv = (DataRowView)e.Item.DataItem; if (drv.Row.Table.Columns.Contains("MerkID"))
But that doenst work because he cant convert it to a datarowview because its a linq class.So what to do? Right now i use a try and catch, but there are better solutions i guess...

When handling the OnUpdateCommand event on a RadGrid the DataItem is null.
I thought that this would also represent the data item being represented by the row.
The Radgrid is populated from an IList and in the handler the code looks like this...
protected void rgAllocatedClients_UpdateCommand(object sender, GridCommandEventArgs e)
{
if (e.Item is GridDataItem)
{
var gridDataItem = e.Item as GridDataItem;
var client= gridDataItem .DataItem as Client;
This works find when handling the ItemDataBound event but not when handling the UpdateCommand event. I really need this as in my Client class is the Id of the row I want to handle the update for.
I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
View 2 Repliesi'm trying to check for an empty cell in a gridview.
On the RowDataBound event I tried the following:
- if (String.IsNullOrEmpty(e.Row.Cells[2].Text.Trim()))
- if (String.IsNullOrEmpty(e.Row.Cells[2].Text))
- if (e.Row.Cells[2].Text == "")
None of them worked.
I'm using boundfields. I can't use a TemplateField with a label because I need to check for other stuff for that column in the RowDataBound event by doing e.Row.Cells[2].Text - that only works if I use boundfields.
I have a sql view of a table, I need to check whether it is empty, if it is empty, I need to hide a grid, other wise I need to show it.
Is there anything useful for me to check the sqldatasource?
