[CLOSED] how can I get GridFilters NumericFilter value on code behind?

[Daniil]

Please clarify have you tried this?

The only way is to send those values from client to server as extra parameters of a request.

Also could you, please, clarify why you need a filter value on server? Do you want to filter the data on server side? If so, please look at this example.
https://examples2.ext.net/#/GridPane...ilters_Remote/

[cottimucin]

Remote filter using sample is;

e.Parameters[this.GridFilters1.ParamPrefix]; using with "Store1_RefreshData(object sender, StoreReadDataEventArgs e)"

 protected void Store1_RefreshData(object sender, StoreReadDataEventArgs e)
    {
        List<object> data = FiltersTestData.Data;

        string s = e.Parameters[this.GridFilters1.ParamPrefix];
        //or with hardcoding - string s = e.Parameters["filter"];
}

can I do this under ext:button click event ?

same as below
how can I do this ?

protected void exportToPdf(object sender, DirectEventArgs e) 
{   
//GridPanel is named MitigationCategories  
//GridFilters is named filterGrid and contains 1 StringFilter against a DataIndex="FE".   
//I would like to be able to determine if the the FE filter is active and if so what its value is.
}

This way:

<ext:Button runat="server" Text="Export To pdf">
    <DirectEvents>
        <Click OnEvent="ExportToPdf">
            <ExtraParams>
                <ext:Parameter 
                    Name="gridFilters" 
                    Value="App.GridPanel1.getFilterPlugin().buildQuery(App.GridPanel1.getFilterPlugin().getFilterData())"
                    Mode="Raw"
                    Encode="true"
                    />
            </ExtraParams>
        </Click>
    </DirectEvents>
</ext:Button>

protected void ExportToPdf(object sender, DirectEventArgs e)
{
    string s = e.ExtraParams["gridFilters"];
}

Hi Daniil,

                            break;

                    }

                }
            }
}

I get error message belove;

[Daniil]

What is the content of the "s" variable when the Exception is thrown?

Could you, please, provide a full test case?

[cottimucin]

content of the "s" variable when the Exception is thrown

[Daniil]

Please try the following.

Replace

Value="#{GridPanel1}.getFilterPlugin().buildQuery(#{GridPanel1}.getFilterPlugin().getFilterData())"

with

Value="#{GridPanel1}.getFilterPlugin().buildQuery(#{GridPanel1}.getFilterPlugin().getFilterData()).filter"

and remove Encode-"true".

thanks daniil everything is all right.
