I didn't had any problem using datagrid to display Sql table on ASP.NET page,
but as the table grows so as the datagrid, and now the item list is too long for one page.
So I would like to break the datagrid into several pages with page numbers. ( <1,2,3,4> click the number to go to next page)
My simple datagrid code:
[Code]....
I would like to make the datagrid bound column to redirecting to the details page .
For example , when my mouse over certain row of bound column in datagrid , it will change the colour to blue . Also , I can click anywhere of the row and the will redirect to the detail page .
Notes : I do not want to use hyperlink column and do not want to fix the text for every row. I want to use datafield, CommandName and CommandArguement.
I have a DDL to filter a gridview by "distance." Works fine, but the list of distances (in the DDL) is getting too long and I would like to norrow it down to "Short", "Medium", and "Long" instead of listing all distances. I have added a column to the Distance table named ClassId and a new table named DClass. I'm having trouble figuring out how to incorporate this idea into my existing DDL-Gridview relationship. Here is the existing code:
[Code]....
I had called the data from query to data table and now i have a gridview in which i am using one datalist and 2 text boxes and and reming coloumns are bounded iahve to assiaign them values which datatable have either null or any value.
View 2 RepliesI am having an issue with a simple databind to a datagrid. What happens is that for some reason, the first character of the data going into the 4th column is getting placed at the end of the data in the third column; but only on the first row. Here is an example of what I mean:
Form ID
Employee No
Associate Name
Start Date
End Date
Form Status
1234
5000187

As you can see, in the first row of data, a "1" has been moved from the Start Date column to the Associate Name column. Because this is a databind I don't see how this is even possible. I'm just curious if this is a known issue or just some random fluke. Here is the relevant code:

i have a datagrid that i want to be able to select a row and be able to edit the details of the row selected. Im connected to an sql azure db.
View 1 RepliesI apologize in advance for my poor english:1. I have a dropdownList within my datagrid and its already populated fine (22 rows in my datagrid)2. The select item for the 21 row is the same as the select item of the 22 row3. When trying to do selectedIndexChange for the 22 row, it didn't seem to work.The error:
Dim ddl As DropDownList = CType(sender, DropDownList)
Dim dgi As DataGridItem = CType(ddl.Parent.Parent, DataGridItem)
Dim rowID As Integer = dgi.ItemIndex
The rowID keep staying at 20 even though the selectedIndexChanged is happening in row 22( ie. rowID should be 21)
I am using list view to display the the data but i am getting an error like An item placeholder must be specified on ListView 'ListView1'. Specify an item placeholder by setting a control's ID property to "itemPlaceholder". The item placeholder control must also specify runat="server.Even i have specified the itemplaceholder id but no use still same error.

I used below code for put scroll for Dropdown list
<script>
function onSelectMouseDown() {
document.getElementById("<%= DDLcity1.ClientID%>").size = 10;
}
</script>
I define label under DDL like below
Now problem is that when I click on DDL to see Item Label that I define jump to bottom of page I mean lable doesn't stay under DDL it jump bottom.
what should I do?
How would I re-code the datagrid below so it displays as a drop down list? The data I want to display in the drop down list is ID="dgvFitters".Also, is it possible to display the data in a datagrid and in a drop down list simultaneously?

This is my first post as a newbie to asp.net.
I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.
What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.
So far my edit page has a datagrid with the following code:
[code]....
I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?
I want to access a dropdown control value of each list item as soon as it is created. I tried with ItemCreated and ItemDataBound events but I am getting null contro when I try to access control as shown below:
ListViewDataItem item = (ListViewDataItem)e.Item;
int LstIndex = item.DataItemIndex;
RadComboBox ddlCategory = (RadComboBox)(listView1.Items[LstIndex].FindControl("rdComboCategory"));
Also, I get listview.item.count zero. IS there any event where I will get listitem count and list items?
I have a simple databound dropdownlist. On top, I have a default selection, '--Please Select--', followed by another default selection, '-- Other --'. Here's the script:
[Code]....
Now, my user wants the '--other--' selection to appear on the BOTTOM of the dropdown as opposed to right sfter '--Please select--'. How do I accomplish this?
I have a databound FormView with a dropdown list of categories. All works as expected, but I want to provide the facility for the user to add a new category to the list and I can't find an elegant way to do it. My current approach is to have a simple modal popup (Ajax toolkit) with a FormView (bound to the Categories table). That successfully inserts the new row, but it doesn't show in the dropdown so it can't be selected. I can force a refresh by calling formview.DataBind() in a suitable event handler, but that of course moves the formview off the selected record and loses any changes the user may have made.
Is there a convenient way (perhaps using AJAX, avoiding a postback entirely) to update the Categories table and refresh the dropdown without moving off of the current FormView's record? I feel sure this
must be a frequent and basic requirement, but I've not found any mention of how to implement it.

i have a dropdown list in edit mode and read only mode. If users upload pictures, i want them to chose a category for the uploaded pics and display it in a gridview as below.(See Picture below). When i include "SelectedValue='<%# Bind("CategoryID")" in edit and item template mode, i get this error "'PictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value "
