I have created a Details View and set some of the fields to read only. I have added the edit command which is allowing me to edit all of the fields that are not set to read only but when I press the update button all the infomation stored in the readomly fields gets deleted and just show up as blank is there a way to stop them from getting deleted.
i have code to update multiple rows in a gridview. What I want is that if the row value is = 1 in the database then the row is checked otherwise it's not. I've put some pseudo code in below to illustrate what I want to achieve.
No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine.
It took me a little while to figure this out, but the AllowPaging="true" on the FormView seems to be the culprit. I don't have much experience paging from a FormView, but for this requirement the customers wants this kind of UI.I have a FormView with DefaultMode="Edit", which is bound to an EntityDataSource. One of the entity's properties, "ExternalID", determines whether some of the other properties in the entity are read-only. For example, if IsExternal==null, the FirstName, LastName, and Email fields should be rendered as TextBoxes. If IsExternal!=null, the 3 properties should be rendered in Label controls.
I have a GridView. One of its columns contains monetary amounts. Underneath the GridView, I have a SqlDataSource which calculates the sum of this column and displays it in a label which is in a DIV called totalsbox (that I have added runat="server" to).
Obviously, if the GridView is empty, I don't want this label to be visible.
In the Page_Load, I have placed the following code:
This works fine. When the Page first loads, if the GridView is empty, the entire DIV is hidden; if not, the DIV is visible and the label displays the column SUM. imagine now the GridView DOES have rows, the DIV is visible and the total is displayed properly in the DIV ("£10.00", say).
I have a RowDeleted event handler in the code behind which contains exactly the same code as I put in the Page_Load. As I delete rows, one by one, the sum is recalculated and displayed properly. But, when I delete the final row, I would expect this code to hide the DIV as the GridView is now empty.
This doesn't happen, however, the DIV remains visible and I have, in the label, something like "£ ".
Why is it that the code works in the Page_Load but not in the RowDeleted event handler?
To write a join query with or condition. It means a query has two inner join, here it is possible to fetch the records, if one inner join is true and other is false. I got a record when only two join conditions are true.
I have a default.aspx page which has two gridview controls i.e. Gridview1 [Displaying Order table] and Gridview2 [displaying OrderDetails table], when I am deleting a row in GridView1, GridView2 should also update its datasource because of referential integrity constraints.
Following is what I am trying to do in GridView2_Load event:
I have wired an event to handle delete command for my GridView. But I cannot determine which the record's unique key, in my case stored in DOCIDNO field. All I get is a row index, such as 0, 1, 2 which obviously cannot be used to accurately delete a record from database.
I have a repeater that has a delete button in it.When the delete button is clicked the panel updates and returns, then the row is deleted.So the deleted row stays in the repeater until i navigate away and then come back to the page. I commented out the update panel and all is good except i really want the update panel as the flicker is not pritt
I have a delete button bellow my gridview and I want a pop up to show when no record is selected and tell the user to first select a record. The button click event would show the pop up, but my gridview data blanks out.
I have a gridview and detailsview that are connected. When I delete records everything works fine except when I delete the last record in the gridview. I want the detailsview to revert to insert mode when I delete the last row in the gridview. Instead the detailsview shows up blank. I want to show the detailsview in insert mode after last row in grid has been deleted? How can do I this?
