Forms Data Controls :: Gridview Need To Get The Value Of A Lable Text?
Feb 11, 2010
I have site where I am listing used equipment. I have a gridview that I have a image field and a template field. In the template field I have the equipment information listed via lables. I also have two link buttons for click for more details and add item to queue. What I am trying to do is when a user clicks on either link button I want to redirect the user to the equipdetails.aspx page based on the EquipID. The problem is that I am getting an errorObject reference not set to an instance of an object. I know that this error is due to the value being nothing. So I need to know how to get the specific row so I can get the correct EquipID. Here is the gridview code and codebehind.
In the gridview I have a column called "% of Points" and another column called "total of pot". Outside of the gridview I have a label called (label Total) and it has a total amount of £6335.
The idea is that as each gridview row is created, it will check the amount in the label and based on the % amount in the % of points, it will work out the total of the pot (£6335) each row has. So for example, paul would have £1583.75 in his total of pot (25% of £6335 = £1583.75)
Anyone know how I should go about doing this? I presume I'd need to do a find control for the label, but not sure where to go from there.
I have this gridview, what I wanted to do is that when the page_load or when the page index changed when the user clicked "Next or Previous" the label change with the gridview. The label and the textbox get the information from the gridview row. It's working but it's alway lagging behind the changed gridview page. Ex: When I click next nothing happen, when I click previous the label changed to the info on the "next" page. O_0This is the code behind.
In my current web application I have a listbox containing large number of elements. I have used an ajax listsearchextender to help the users in selecting the elements. I have set the autopostback property of listbox true. The application is working fine as expected in internet explorer. But in firefox while I am typing some text in search lable of listsearchextender the selectedIndexChanged event is fired and the page is posted back. So I am not able to selected the item properly using list search extender control. Can you please suggest me how can I stop the selectedIndexChanged event.
I'm trying to get the text value of a label when that row is selected in my gridview. The label's text is databound. Originally when I used the <ASP:BoundField /> I retrieved the data by using this syntax "Server.HtmlDecode(row.Cells[1].Text )" when an "onrowcommand" event is triggered. My question is what is the syntax to retrieve the text value of this label if I am using a template field in my gridview. The code for my label is below.
I am printing a GridView on a Panel using the PrintHelper sample code. Two issues arise from the result. One: I would like to print the text of one column, without the hypertext underlining. Two: I would like to print strings ("Active" or "Inactive") for one column instead of a CheckBox.
I have big problem I have a table where the column is "Enabled" datatype = bit.
In this column I have data True / False. The show GridView column 'Enabled'. Problem is, as everywhere in this column, write True / False. How, in view of this information in the GridView displayed: True = Verified, False / UnVerified GridView, column is "Enabled"
Column Enabled: No False No True Column Enabled I want this Unverified Verified
It should probably change the text, or something like that.
I'm displaynig plain text in a Gridview and the format is not the one I'm looking for here's what's happening. The data in the database (SQL) is store as sample1
Sample 1:
Please do the following:
1. text here and more text 2. blah blah blah 3. more text, etc
However in the Grid view is displayed like this:
Sample 2:
Please do the following: 1. text here and more text 2. blah blah blah 3. more text, etc
I have a 3 text boxes. When i enter datas in and click the button it displays the gridview with filtered data. Now my problem is if there is no data in gridview it has to show "no data" so I used emptydatatext property.. The problem is, in the page load itself it shows "no data"
I have the grid view with boundfield with four columns. I created the text box when gridview row created event. I need to filter the data the gridview using the textbox and need to know the how to generate event for textbox.
1. First i am populating a datatable with two columns of type text. The second column is a hyperlink (but i am not specifying that datacolumn type as hyperlink).
2. After populating the rows, i am adding the datatable to dataset.
3. then binding this dataset to the gridview (the gridview's AutoGenerateColumns=true).
Question:
Obviously, the hyperlink column is represented as text in the gridview (non-clickable hyperlink).
here i am trying to convert this hyperlink column (data rows), from text to a hyperlink, so that the user can click directly and navigate to that url.
FYI, I cannot change this method of binding, and just want to convert this text hyperlink to a real hyperlink.
I have seen several Web Sites that use GridViews that have lookup fields with different Value and Text Fields (as in drop down lists) but I can't seem to figure it out how to display the Text Field in the Item Template when the Text Field is not in the datasource. .
Here's what I have. I have a Gridview whose datasource is a Linq to SQL Invoice table, e.g.
InvoiceID CustomerID InvoiceNumber
THe Customer table is related to the Invoice Table thru the CustomerID. The relationship is defined in SQL Server and is displayed in the DBML.
I have created a template field for the CustomerID field in the Gridview. I would like to display the CustomerName when the Item Template is displayed and a DropDownList in the Edit Template. The DropDownList works great, but I cannot seem to figure out how to display the CustomerName in then Item Template.
I seem to remember seeing in some video that you can simply drag the CustomerName into the CustomerID Item Template Field. But I can't seem to find the customerName field. The DataSource includes the Customer Table because of the relationship, but no fields are displayed.
I suspect this is real simple, but I cannot seem to find an article or video that explains how to do this.
I just hit the same problem as described here: [URL] - GridView paging with ObjectDataSource. I see the column headers but no data, and I know for a fact my method returns a DataTable with data in it.
I created a database with ID, Title, Content, Date, ImgLnks, Image and Imagecaption and i'm using ObjectDataSource to populate the data. The field "ImgLnks" displays a new blank window with URL. This column is entered as text, inserted into the database and displays as clickable link in the gridview. My question is, is there a way that I can put an Alternative Standard Text in this column instead of displaying the clickable link like [URL] etc.? Text like, "Visit Page".
