Forms Data Controls :: E.ExceptionHandled Not Stopping Data Binding?
Feb 11, 2010
I have a gridview with an objectdatasource whose select method calls a stored procedure. In the select method I test for an output parameter from the stored proc which can indicate certain business rule problems, such as no rows returned. I throw an exception in the select method in these cases which bubbles back to the selected event of the objectdatasource.
In objectdatasource.selected, I set e.ExceptionHandled = True, so that further processing of the gridview stops, including databinding.
The problem I have is that the objectdatasource select method executes again, even though I have set e.ExceptionHandled to true. This then cause problems with my messaging to the user. Am I missing something about the purpose of e.ExceptionHandled.
Two questions. First, is HeaderStyle-Width a preferred/best way to manage column width in a grid view? And second, how do I suppress the genration of the the additional code?
I have a GridView and the users are complaining about the columns shifting around. The width of the columns automatically adjusts to fit the size of their contents, and expand as the page is made bigger.I need to be able to set the width of the column so that it takes up the same size, regardless of the size of the contents or size of the page.I am using templated in my grid, but there is not width attribute
sp:TemplateField> or in <HeaderTemplate> or <ItemTemplate>
I have created a simple dataset with my ObjcetDataSource to my SQL table named Invoices and a new FormView. My form inserts are working 100% correctly, however after some testing i noticed the insert happens again if i hit the refresh button on my browser after an initial insert. I am currently submitting the form back to itself with a success/fail message returned on the page so that the user can keep inserting more records if they choose. This is done in my Inserted behaviour.
In my ObjectDataSource_Inserting code i am setting the values of a date prior to my insert. How do i stop a second INSERT from happening when the user refreshes the browser? I thought it was what IsPostBack was used for? Here is my code:
.I have a search page where I would search for an item and it would dispaly the results in a gridview...
I have allowed paging and set page size to 10..now I can see the 10 results in the first page and also see the page numbers at the bottom of gridview. But now when i click on the page 2, the method gridview_pageindexchanging is triggered but the result set is not dispalyed. My code is as below..
[code]....
i understand that the data is not binding in the GridView1_PageIndexChanging method..I do not know how can I make data bind..
I'm trying to build a chart in my application which will act as a client for an ASP.NET 3.5 web service that I created. The error I get is as follows:
Series data points do not support values of type System.Data.DataViewManagerListItemTypeDescriptor only values of these types can be used: Double, Decimal, Single, int, long, uint, ulong, String, DateTime, short, ushort.
I've tried various ways to resolve this but can't. This error points at the chtStats.DataBind() line in the code below:
I have a GridView or DetailsView and its bound to a CslaDataSource.I noticed that the "Object_Select()" event is fired automatically with every time the page is loaded or refreshed.How I can perfrom mnaual biding between the DetailsView Control and CslaDataSource ?I want to control binding via code using the DetailsView.DataBind() method in certain cases only.
not quit sure where I've go wrong with this but hopefully someone might have an idea why this isn't working:
This what I thought would work:
[code]....
But it's not! what I get for the OnClientClick attribute is: "DeleteRowKey=<%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> "
I've tried several variations (EVAL, BIND, specifying the container and not specifying the container),
none of which gives the expected results; OnClientClick="DeleteKeyRow=12345"
If I add a label and set the text to: <%# dataBinder.Eval(Container.dataItem, "idx_mstrWord") %> I get a number which is what I should but if I try to get it to embed it so my cleint script can work with the data all I get is binding command.
What am I doing wrong? I really don't want to have to kludge around with some hidden field and then have to search through the grid to get at this data key. I need this key on the client side in order to provide additional details in my confirmation popup modal.
I have a repeater control populated with data binding expressions like in the expression below...
[Code]....
I want to be able to redirect a user to default link if the LinkURL value is empty, that is for each data item, there will be a check if the LinkURL field contains a value. If not, a default value will be supplied.
I ran into this kind of situation many times without a nice solution. Binding a data source to a gridview and one of the column require nested query. Is it possible to have a callback function other than Eval()?
I have a Data Table which Populate from the Stored Procedure which is below
[Code]....
and iam binding the Gridview with Data Table it is working .Now i have to make some thing visible and Invisible based upon some Value like below
Datatable dtTable = (Viewstate)["StatusData"]; // Same Data Table which is Data Source of Gridview Control [Code]....
Where Status.Open is an integer Enum value like Open = 1 and Close = 2 .row["Status"] is the Text Open and i want to compare with integer valueHow i compare the Values ? i have to use the same Data table or not?
in other words, reading the content (records that lies within) of a LinqDataSource object programatically (i.e. similar to what the GridView class does internally when binding to a LinqDataSource object).
I have a grid which is binding to a objectdatasource and when it is in edit mode, i am displaying a form template and wanted to bind all the values. I have one field called ApprovedCode. In the edit mode, i am displaying all the codes drop down list box and making a bind on the selectedvalue and i dont know how to handle when it is empty. When it is empty i wanted to display "Select..."
I followed this forum post but i am getting error
[URL]
This is my code
[Code]....
This is the error message that i am receiving
"ddlApprCode' has a selectedvalue which is invalid because it does not exist in the list of items
I have a DataGrid bound to an ObjectDataSource, as you know once the DataSourceID on DataGrid is set, data binding happen automatically without any coding. But due to requests from end users, I need to prevent the data binding when the page is loaded the first time, i.e. data binding should only happen during PostBack. How do I do that?
When i bind gridview to stored procedure what i found it only shows data after enabling Autogeneratecolumns and it also doesnot show any column in boundedfield. Due to which i am unable to apply formating to individual column according to my requirement. One possible reason may be table is created in stored procedure due to which it generate fields at run time.
I have seen several post on this but I cant seem to make any head way. I have a createUserWizard that creates a user and on my CompleteWizardStep I have a drop down that needs data bound to it. The error I am getting is 'Object reference not set to an instance of an object.' Null referenctException my code is:
Dim iSavesCounties As New dsISavesTableAdapters.tbl_countiesTableAdapter Dim ddNewCounties As DropDownList ddNewCounties = CType(CreateUserWizardStep1.ContentTemplateContainer.FindControl("ddCounties"), DropDownList) ddNewCounties.DataSource = iSavesCounties.GetData() ddNewCounties.DataTextField = "countyName" ddNewCounties.DataValueField = "countyId" ddNewCounties.DataBind() Dim iSavesCounties As New dsISavesTableAdapters.tbl_countiesTableAdapter
I have a details view in asp.net which I am dynamically replacing some of the controls using code behind (e.g. converting some text boxes to dropdowns). My problem is that I am unsure how to bind these to the field from the database on postback. I.e. I am trying to find the code behind equivalent bind('currency');
I can populate the dropdown with the current value from the database but cannot find how to save a new value on updating the detailsview.
I am binding same data Table to Combo box and List Box on the WindowsForm Load.
When I select a value in Combo box automatically that value is also getting selected in List Box and same thing when I select a value in List Box that value is also getting selected in Combo Box.
Selection should be only for that particular control, how can I achieve this ?
I'm a bit of an ASP.NET newbie and I am creating a data table in memory and binding this to a gridview control. The code is as follows:
Dim DstBasket As New DataSet, TblBasket As New DataTable With TblBasket .Columns.Add("BskPrdCd", System.Type.GetType("System.String")) .Columns.Add("BskPrdDesc", System.Type.GetType("System.String")) .Columns.Add("BskQty", System.Type.GetType("System.Int16")) .LoadDataRow(Split("12345,Test product 1,1", ","), True) .LoadDataRow(Split("122,Test product 2,2", ","), True) .LoadDataRow(Split("123A,Test product 3,5", ","), True) .LoadDataRow(Split("44,Test product 4,1", ","), True) End With DstBasket.Tables.Add(TblBasket) With LfnGridView("GdvBasket") .DataSource = DstBasket .DataBind() End With
The data displays in the gridview control fine with both edit & delete options but when I attempt to delete, it has no effect. How do I force removal of the relevant row from both gridview and table? Most of the documentation I have unearthed shows how to achieve this when connected to a SQL table which is clearly not the case here.
