I want to created a messaging system and to display the messages. I want to use a gridview. My problem is how can I display the new messages in BOLD rows and the readed messages in normal text.
View 7 Replies I have a simple problem. What i wish to do is to read the data bound item [Code]....
and if the output = 0 then rather than display the 0 I would like to display a message such as Not Available.
Can anyone provide a solution?
I have two databound listboxes. I am able to move items between them using add and remove buttons using for loops. However I have no idea how to commit the items back to the db when the user finally clicks on the Save button on the form.
View 5 Replies I have a DDL bound to a sqlDataSource, and I want to insert an item in the first position. I tried using this code in the onDatabound event:
Protected Sub ddl_onDataBound(ByVal sender As Object, ByVal e As EventArgs) Handles ddl.DataBound
ddl.Items.Insert(0, "None")
End Sub
But when I load the page, the item "None" is inserted twice at the beginning of the DDL? So I see something like:
None
None
item1
item2
Do I need to put the items.insert somewhere else, like on the pageLoad, to avoid it being executed twice, or am I doing something really wrong?
have an annoying problem. i'm trying to update single items in a databound listview. but when i click the update button it gives me the cannot insert NULL value. it doesnt seem to read anything from the textboxes which i have databound from the database. even though text is clearly shown...
i have setup my update statement and parameters, it uses the Update command name and ItemUpdating event. i catch the data from the textboxes by using e.ItemIndex and use the text assigned to the parameters in a SqlCommand.
The thing i'm aiming for too is that when an item is updated it stays on the page where the item was updated, (i was using response.redirect before but it went against my aim since the whole page reloaded)
I have a gridview control having the following columns.

On the basis of SchedularID i want to compare the value in column total and make the one with higher value as bold. But the problem is i am calculate the Total column at run time inside Row databound even. So any solutions?

I have given an access to stored procedure, which i'm not able to edit. This Stored Procedure returns a Table with 2 Column, what I did is set a GridView's DataSource using SQLDataSource in this stored procedure. but I want this GridView to Sort an specific column to descending whenever this GridView Loads.
<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource2" ForeColor="Black"
Width="58%" Height="125px" AllowPaging="True" AllowSorting="True"

I'd like to make some words of a cell in gridview Bold. For example - "MRN No.: SI0021848 Name: Cherry" like my attachment. I could query this field value from database but don't know how to make some words Bold. How to do it?
View 2 RepliesI would like to know why somethimes DefaultValue in properties window is displayed in bold text and somethimes in normal weight text? What i know is that the Value in Properties Window should display bold only if the Value is different than DefaultValue.
So i have a situation, where i need to set DefaultValue's and i'm successfully setting the boolean Value but failing in Integer value...
aspx:
[Code]....
Now the reason why i'm using Int32 in this example is that i hovered the mouse over the DefaultValue and it's said that "represents a 32-bit signed integer" but still no luck.
Why is my StepHour displayed bold and how to display this DefaultValue in regular weight text?
I have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"

I'm working with a custom DropDownList control in ASP.Net and there's been a request to display certain items in the list with a bold typeface (NOTE - the control inherits from CompositeDataBoundControl so it can be data bound... not DropDownListBox). The control is bound to a table and there's a column in the table named IsUsed - if this is set to true, the corresponding item in the list should be rendered bold. (It should be noted here that this will only ever be viewed in FireFox.)
My experience is all in the middle backend tiers so the presentation layer is very new to me - can someone point me in the right direction? My initial thought was that somewhere in the custom control I would have access to all the rows that are returned from the data source which I could cycle through etc but I'm not sure if that's possible... There's also RenderContents which I can override... looks interesting!
i have to a grid view and the datasource for it is a table coming from the database the table containing sequence numbers for example if the sequence number is 1 then i want to add a row just above this saying it is the start , the entire row should give some information .
i tried to find related thing but no luck, waiting for some replies to move further
I need to be able to get the value in the "first" row of a Gridview as its getting or right after it is displayed.
I thought this would work but its coming up null.
I'm using the DataBound event to get the value of the control of a selected row...assuming the selected row is the first row which is probably the error of my ways. Any ideas how to get at this value easily?

I have two gridviews, where the first is databound to a sql table (but does not display the primary key info), and want to filter the data displayed on the second gridview by using the primary key info from the first gridview table, indicated by the selected row in the first gridview - how I could achieve this? its kind of like using the gridviews as a menu and sub menu display!

So I am uding a GridView bound to a SQL data source.
I have a template feild bound to a SQL BIT
<EditItemTemplate <asp:CheckBox ID="chkSelected" runat="server" Checked='<%# Bind("Selected") %>
The original Item Template was Enabled ="false" I changed this so that you did not have to set the row to a state of edit in order to just select a row. I enabled it so that you could "select" any row with out putting it in a state of edit. the only value changing is if its selected or not. What i am trying to do is use the Data Source Update method to update the bit in the database based on the check box. Currently Update() returns 0. I believe this is because the row/feild is not marked as changed so the Data Source does not see it as something that needs to be updated.
What I am hoping for out of this is post is a way that the rows whom check value has changed to be marked as changed/edited so that the data source will update the database with the values of the check boxes. If all rows are updated this is acceptable as well. I know this is a super simple solution but i have been out of the .NET for a little bit.
I am facing certain problems with the data formatting in GridView when the data is bound dynamically to it.
I have a DateTime column and want to only show Date from it and not the time.
Another Decimal type column which accepts decimal upto 4 places, I want to show decimal upto the places defined in the particular value (don't know how to put it in the correct way, but here is an example of what I want).
i.e.
1.0000 should be displayed as 1 after the databound in the gridview.
Similarly,
2.3400 --> 2.34
1.0050 --> 1.005
1.1000 --> 1.1
im building a simple message messenger web application, i currently have a column in my database dedicated to the status of a message. Its bound to the third column in a datagrid.
After converting the column to a TemplateField and using a Label to fetch the data how do i change the text from the database to a small message, e.g. if the data in the database (as an interger) is 0. how do i change the interger to a string to display "UnRead". Do i need to do this during the databinding call or after the grid has been databound?
I know it would be easier to use a boolean and checkbox control but the interger column represents more values than true or false.
I have a stored procedure (For Eg: sp_GetAvlData) that accepts a number of parameters, 3 of which are TimeFrom, TimeTo (as varchar) and TimeInterval (as int), formulates a Dynamic query and executes itself. So for instance, if I call the proc as follows:
[code]....
dtAvl is the datatable containing the results of my stored procedure.
The next step for me is to make each of the cells (except the cells in the first column) as a Hyperlink so that when clicked upon a cell, it populates 2 textboxes with the selected Timeslot and Name or ID (ID field is not displayed in Gridview). The textboxes are located on the same page but outside of the Gridview control.
The Challenge that I'm facing out here are:
1) As you can see, the field names being generated are not fixed and I have no control over them.
2) Because the field names are not fixed I'm not sure I can implement this using the Templatefields or BoundFields of Gridview.
Is there any way to achieve the Hyperlinking of these cells within the Gridview?
I have a data gridview with two columns (Databound- HTML tags), very similar to the one of twitter,the second column populated as follows:
USERNAME: COMMENTDate
i need to add "Report this Comment" button next to the date, once clicked the user will be forward it to another form holding all of the above information related to this special row.
So I have a ListView (assignmentsListView) in an UpdatePanel, being filtered by a DropDownList in the same UpdatePanel. The DropDownList has a list of persons in it and uses autopostback, and the ListView shows the tasks those persons are assigned to.
I am trying to use code similar to this:
[code]....
When I first load the page, the DropDownList shows the first person in the list, and the ListView correctly shows that persons tasks.
If I then select a person who I know has zero tasks, I get an error at the RegisterPostBackControl() method, saying the passed-in control cannot be null.
When debugging, at the RegisterPostBackControl method, it shows that the ListView Items collection has >0 elements in it (the number of elements matches the person selected before the current person).
I have a datagridview that has a column which displays a ref value from another unbound table, but during an edit of a gridview entry i want a dropdownlistbox to list all the available ref values from the other unbound table source, then to insert the selected value into the bound table
