Forms Data Controls :: OnCheckChanged Is Called When GridView Column Is Not Visible?
Oct 18, 2010
The example .aspx page below includes a grid containing two checkboxes. The first is hidden because its ItemTemplate.Visible is set to false. What is the cleanest way to avoid OnCheckChanged when the parent cell is not Visible?Paste sample below into new .aspx and run. Uncheck 'Visible' Click 'Test'Expected Results (since only the 'Visible' checkbox was changed):
Now the issue is that that every document doesn't has document number. I want to make invisible the docuNumber column of the grid viwe if all values in the docNumber retrieved are null.for example:
docnumber tite null Document 1
null Document 2
null doucment 3
null document 4
if returned result match above where all docnumber are null then make the gridviwe docnumber column ivisible eslemake the greidviwe column visible.
I have a Data Grid View which display values from a SQL Query, and inside the data grid view I have two template fields one is Quantity and it is a text box and the other is Total Price and it is a label.
What I want to do is to insert a button called update and when I press this button the price Column should be multiplied by the quantity Column and the result should be displayed in the total Column.
I have a GridView and provide the user with sorting, paging, editing, deleting and selecting functionality.
When the user klicks the delete-button in the GridView, the Row-Deleting event is triggered, the record is correctly deleted from Database after user confirmation. Then the Row-Deleted event is triggered and afterwards the Row-Deleting event is triggered AGAIN, resulting in a second user confirmation and a Delete-instruction running into void if the user confirm again the question.
Between the Row-Deleted event and the second Row-Deleting event I saw the GridView binds his data again (comprehensible because it wants to provide an updated view to the data), maybe somwhow there is generated or provoced the second Row-Deleting event.
I want to display gridview column heading when mouse over to the particular column in the gridview.I am working in VisualStudio 2005 with MS.Net2.0 framework.I don't want to use ajax.
I have a customized gridvew i.e. grvResult. There is a textbox and a InsertButton in the footer.
If there is a data populated into gridview it is showing GridView footer and inserting data but if there is no data in gridview then its footer also not visible.
I have tried in two ways to make footer visible but it is showing following error:
Object reference not set to an instance of an object.
I have a gridview which is binded to a Sqldatasource. I would like to replace a column data field value to 'Not Applicable' if that column has got a value of 2 in database.
i have gridview with linkbutton.when i click linkbutton it should call javascript function which returns value would be input for database functions. how do i capture javascript function retun value(i am using Registerclientscriptblock)? and that should be input for database function. Inshort i need to call two function from link button click - one javascript function,one ado.net function which will update value in database. output of javascript function will be input for database function.
function Getlogitudelantitude(address) { return "35.3434343,-74.334343" } Linkbutton_click(object sender,Eventargs e) { register javascript function .. which should return value string s = "35.34343,-74.334343" then call database function(s) - does database operation } }
I have been researching this issue for a couple of days and have found a lot written about it, but none of what I have found has fixed the problem I am having.
I work for a school system, and my principals are wanting to take a list of the staff members at their school and create staff lists for different activities they perform. I thought I would load the staff into Gridveiw1, and when they select a record have it move over into Gridview2 and "delete" from Gridview1.
I am loading my full staff into a datatable (SQL Server backend), and setting this datatable as my gridview1 datasource. At this point, it loads great, and cosmetically speaking sorts and pages fine. The problem occurs in the codebehind after a Sort or Page change has occurred -- when I select a record and move it over into Gridview2, it is moving the original record that was at that postion on Page 1 instead of the sorted or "new page" record.
So if the initial list comes in as:
Teacher 1 Teacher 2 Teacher 3
The sort button is hit so that the list now starts out like:
Teacher 7 Teacher 13 Teacher 5
If they select "Teacher 13" to be moved over after the sort, instead it is still moving over "Teacher 2" -- the initial teacher in that index before the sort.
The Gridview setup on my aspx page looks like this:
I have a master/detail page using a gridview as the master, and a detailsview as the details. The gridview is set to select a record, and the detailsview picks up the ID and you can either edit that record, or add a new one.The detailsview is set up with various template fields, and if everything on the page is visible, it works OK.However, I wanted to hide the Gridview when the user in working with the detailsview. But if I do that, the detailsview doesn't update the record.
Whenever you turn off the visibility of a column in Gridview, on Edit, the value becomes null because its never bound. The only way I know of stopping this behavoir is to put it in the DataKeyName list. Is there any other way to prevent this? I have quite a few columns that will not be displayed in this "release" but I want there for future extensibility. Also, in some cases these values will be used for calculations but the user should not see them. Is there no toggle property for "non-visible" items to remain "unchanged" or something of the sort?
I have an Outer gridview (called grdvOUTERGRIDVIEW) and an Inner Gridview (called grdvOUTERGRIDVIEW) and I am able to see and use the outer gridview in my codep-behind vb page however when I try to handle an event for the Inner gridview then I get the warning: "handles clause requires a withevents variable defined in the containing type or one of its base types".
After creating the inner gridview I closed the page out and re-opened it however still getting that error and not able to create the grdvINNERGRIDVIEW.RowDataBound event function like I am trying to do.
I am using GridView ,I want to do a validation like if i edit any one of the Cell in that column, it will through the validation when the sum of column value is more than 100. How can i do this validation?
