Forms Data Controls :: Change The Databound Field On A Grid?
Mar 6, 2011
I have to modify a page so that depending on who views the page i will show client or client Type, its easy enough to change the text but I cant see how to change the datafield
It happened to add an extra Gridveiw Header in row_databound event , It did worked fine on !Postback but disappered on Page.Postback . Quick google search guided me to move the event to Row_Created event and every thing is okay .
Can any expert post some pointers , differnces between grid row_created vs row_databount with some sample table data created dynamically behaviour of both the events in !Postback and page.Postback .
I have an "effectivedate" field that is displayed using a label inside a detailsview control... In the code behind I need to add 12 months to this to check if a policy is up for renewal or not...
To find the control I use this code... Dim EffectiveDate As Label = DetailsView1.FindControl("EffectiveDatelbl").ToString But when I try and convert the label to datetime type using this... Dim ExpireDate As DateTime = EffectiveDate.AddMonths(12)
I get the error - Cannot convert string to date, addmonths is not a member of label etc...
How would I go about displaying a databound dropdown list in a property grid, i.e. a dynamic list that can be used to set the value of an individual property?
I would like to count the number of page views. I am able to use the global.asax file and a label to obtain this. However, this gives me the total count of the page. That is great, however I like to count the number of users accessing the page when the user clicks on a particular gridview row value from the previous page.
I have a gridview in the gridview a value that links to a new page. This new page contains the row values. I would like to count the number of users who have accessed this new page based on the gridview row value. As such the page count will be different based on each row.
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'm using a gridview to extract a set of records. I need to add another field to the gridview, which can calculate the difference between a date associated with each record and the current date.
I have a gridview in which I have several editable fields. The user wants a non-editable field to be modified if another field is modified in the same row. e.g. if Age>=65, Status should ="Retired"
I am using the following demo: [URL]
to create a bulk edit gridview so some columns are automatically editable and others aren't, with a single update button. I can set Status="Retired" in the xml generated, or as a rule in database table. But I'd like the status field in the gridview to change when Age is modified and to be shown to user before they press the single Update button. I'm using update panels and ajax on the page also.
What I would like to do is show only the Name and IsReadonly and hide the Key field .
I think u can use a it as a Date Key or something because i then want to delete a record (using autogeneratedeletecolumn)and use that Key in the where clause.
I have a grid view with several TemplateFields. A couple of them are set to Visible=False; each template field has an EditItemTemplate, an ItemTemplate and a FooterTemplate.
[Code]....
While in GridView_RowUpdating event, the value bounded to the EditItemTemplate is properly read
[Code]....
so, debugging ttbImp.Text = "4"; But when trying to get the value bounded to the FooterTemplate, the label contains no values.
[Code]....
so, while debugging, lblImp.Text = "";
why that? I believe it has to do with the hidden visibility of the field, but I can't understand why it reads the value inEditItemTemplate, and it doesn't in FooterTemplate.
I want make one of the field in my data grid in hyperlink after I retrieve the records from the database. I have EmpId and EmpName in the gridview but I want to make the EmpName field in hyperlink so that when I click a name, I can redirect at a page based on the data of that field. How can I suppose to do it??.

I know that variations of this same question have been posed numerous times - but I can't quite seem to find the exact solution.
I would like any row in my gridview where the boolean field "Approved" is True to be shaded gray. Here is the code that I'm using, but every row ends up being gray, regardless of the value in that "Approved" field. My guess is that I'm not correctly evaluating the boolean value in this field (which is actually a yes/no field in MS Access), Not sure if I should be reading that value as "-1", "Yes" or "True" or "NotNull"? Anyway, here is the code:
I have developed my application using Visual Web Developer 2008 express with Visual Basic code.
If I am working with 2 textboxs on a form, and I set the "Autopostback" to "true" for the first texbox then on the "changed" event, I can just add code to set the visibility to "true or "false" for the second textbox - it works fine. However, I do not seem to be able to figure out how to do the same thing when I am using a Dataview.
I have a table called "Customer" that contains 4 fields "CustomerName", "BasePrice", "LevelOfActivity", and "Discount".
My user enters information into this table using a Dataview form that displays the 4 fields.
When the user enters the value "L" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "false" - (I want to hide the field as this customer should not get a discount). If the user enters the value "H" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "true" - (I want to show the field so the user can enter the "Discount").
You'll have to excuse my ignorance, I'm coming at this from a front-end perspective, and don't really know how to deal with data views in ASP.NET.
Basically, I'm trying to change the layout of some repeated data from a straight table, to something more design-heavy. It's the same data, just re-organised slightly. The current ASP.NET code looks like this:
[Code]....
However, I want to replace all of this, such that each 'row' of data renders like this:
[Code]....
How is this done? Can I just edit the code above, or would I need to do something more advanced in terms of not using a data grid and using some other control instead? Is it something that can be done in just a .aspx file or would it need to be done in C# and compiled?
I have a grid view that displays some diary data that consists of a date, a diary entry and a diary entry type (eg holiday, info, meeting..)How can I change the background colour of a row depending on the diary entry type.So for example if the type is 'holiday' colour the row yellow, if its 'meeting' colour it red etc etc
